California's K-12 schools contain 40% of the nation's English learners, the majority of them enrolled at the elementary level. Traditionally, English learners in California have difficulty performing at the same level as their native English speaking counterparts on national achievement tests, such as the National Assessment of Educational Progress. In 1998, California voters passed Proposition 227 mandating that English learners be taught "overwhelmingly" in English, thus making teachers, many without expertise, responsible for teaching multilevel English proficient students subject matter. I studied the use of scientist-teacher partnerships as a resource for teachers of English learners. University scientists (graduate students) partnered with local elementary school teachers designed and implemented integrated science and English lessons for classrooms with at least 30% English learners. The study explored two major foci. First, integrated science and language lessons implemented by six scientist-teacher partnerships were investigated. Second, the responsibilities taken on by the team members during the implementation of integrated science and language lessons were examined. Three data sources were analyzed: (1) six lesson sequences comprised of 28 lessons; (2) 18 lesson worksheet; and (3) 24 participant Retrospective interview transcripts (12 scientists and 12 teachers). Lessons across were examined according to four analytical categories which included the following: (1) nature of the science activities (e.g. hands-on); nature of language activities (e.g. speaking); (2) nature of instructional practices (e.g. student grouping); and (3) responsibilities of teachers and scientists (e.g. classroom). A micro level analysis illustrates how one scientist-teacher team innovatively used a children's story, Goldilocks and the Three Bears, to teach the measurement of length and temperature. A macro level analysis identified three characteristics of science activities

In 2006 the author organized a one-day intervention aimed at promoting physics among female learners at the University of Stellenbosch. The activities included an interactive lecture demonstration promoting active engagement, a hands-on session, and short presentations by female physicists addressing issues such as balancing family and career, breaking the stereotypes, and launching a successful career in physics. Each learner was expected to evaluate the program. In 2007 the author joined forces with Hip2B2 (Shuttleworth Foundation) to host a competition among grade-10 learners with the theme, ``promoting creativity through interactivity.'' The author was tasked by the Hip2B2-team to assist with a program for female learners planned for August 2008, coinciding with our national celebration of Women's Day. The event targeted 160 learners and took place in Durban, East London, Cape Town, and Johannesburg. The author shares some of the learners' experiences and personal triumphs.

A large body of literature has characterized unimodal monolingual and bilingual lexicons and how neighborhood density affects lexical access; however there have been relatively fewer studies that generalize these findings to bimodal (M2) second language (L2) learners of sign languages. The goal of the current study was to investigate parallel language activation in M2L2 learners of sign language and to characterize the influence of spoken language and sign language neighborhood density on the activation of ASL signs. A priming paradigm was used in which the neighbors of the sign target were activated with a spoken English word and compared the activation of the targets in sparse and dense neighborhoods. Neighborhood density effects in auditory primed lexical decision task were then compared to previous reports of native deaf signers who were only processing sign language. Results indicated reversed neighborhood density effects in M2L2 learners relative to those in deaf signers such that there were inhibitory effects of handshape density and facilitatory effects of location density. Additionally, increased inhibition for signs in dense handshape neighborhoods was greater for high proficiency L2 learners. These findings support recent models of the hearing bimodal bilingual lexicon, which posit lateral links between spoken language and sign language lexical representations.

The economy continues to sputter along, and the repercussions are now hitting hard at publicly-funded colleges and universities, with enrollment increasing and funding decreasing. Funding agencies are starting to look at retention and completion rates as a way to allocate scarce dollars. Improving these rates is also one way to increase the future stream of tuition; students who can't pass introductory classes like ASTRO101 won't enroll and pay tuition for the next level, and they won't complete their degree. So what can you, a mere professor of astronomy, do? Tired of the "What do you want me to know?" questions? Provide your students with learner-centered structures to help them learn more deeply. Do your students resist active-engagement techniques and hate group work? Share empowerment strategies for helping students become active, responsible learners who can thrive in a learner-centered environment. Do you think that it's wrong for the freshman classes to be over-crowded, yet your sophomore classes don't get enough students or don't even exist? After using the proven curriculum of On Course, college and universities across the country have improved their retention across a wide range of disciplines (http://www.OnCourseWorkshop.com/Data.htm). Experience a sample of the fun and engaging activities developed over two decades to help students (1) accept personal responsibility, (2) discover self motivation, (3) master self-management, (4) use interdependence, (5) gain self-awareness, (6) adopt lifelong learning, (7) develop emotional intelligence, and (8) believe in themselves. Since this is only a one-hour workshop, we will focus on choices one and four: to be successful, students need to see themselves as the primary cause of their outcomes and experiences and to build mutually supportive relationships in our classroom and labs. Outcomes: (1) one ASTRO101 Course-ready activity to help students accept personal responsibility; (2) one ASTRO101 Course

Many studies and systems that incorporate elements such as “pleasure” and “fun” in the game to improve a learner's motivation have been developed in the field of learning environments. However, few are the studies of situations where many learners gather at a single computer and participate in a game-based learning environment (GBLE), and where the GBLE designs the learning process by controlling the interactions between learners such as competition, collaboration, and learning by teaching. Therefore, the purpose of this study is to propose a framework of educational control that induces and activates interaction between learners intentionally to create a learning opportunity that is based on the knowledge understanding model of each learner. In this paper, we explain the design philosophy and the framework of our GBLE called “Who becomes the king in the country of mathematics?” from a game viewpoint and describe the method of learning support control in the learning environment. In addition, we report the results of the learning experiment with our GBLE, which we carried out in a junior high school, and include some comments by a principal and a teacher. From the results of the experiment and some comments, we noticed that a game may play a significant role in weakening the learning relationship among students and creating new relationships in the world of the game. Furthermore, we discovered that learning support control of the GBLE has led to activation of the interaction between learners to some extent.
Teachers' informal discussions of learner motivation often emphasize the need to find ways to motivate learners, most usually through "fun" or "dynamic" activities. This paper starts from the assumption, however, that part of the work of the teacher is to avoid the "demotivation" of learners, and that there is a need to consider the overall…

This functional magnetic resonance imaging (fMRI) study investigated the brain regions underlying language task performance in adult second language (L2) learners. Specifically, we identified brain regions where the level of activation was associated with L2 fluency levels. Thirty Japanese-speaking adults participated in the study. All participants were L2 learners of English and had achieved varying levels of fluency, as determined by a standardized L2 English proficiency test, the Versant English Test (Pearson Education Inc., 2011). When participants performed the oral sentence building task from the production tasks administered, the dorsal part of the left inferior frontal gyrus (dIFG) showed activation patterns that differed depending on the L2 fluency levels: The more fluent the participants were, the more dIFG activation decreased. This decreased activation of the dIFG might reflect the increased automaticity of a syntactic building process. In contrast, when participants performed an oral story comprehension task, the left posterior superior temporal gyrus (pSTG) showed increased activation with higher fluency levels. This suggests that the learners with higher L2 fluency were actively engaged in post-syntactic integration processing supported by the left pSTG. These data imply that L2 fluency predicts neural resource allocation during language comprehension tasks as well as in production tasks. This study sheds light on the neural underpinnings of L2 learning by identifying the brain regions recruited during different language tasks across different modalities (production vs. comprehension).

Video and photography are often used for delivering content within the anatomical sciences. However, instructors typically produce these resources to provide instructional or procedural information. Although the benefits of learner-generated content have been explored within educational research, virtually no studies have investigated the use of learner-generated video and photograph content within anatomy dissection laboratories. This study outlines an activity involving learner-generated video diaries and learner-generated photograph assignments produced during anatomy laboratory sessions. The learner-generated photographs and videos provided instructors with a means of formative assessment and allowed instructors to identify evidence of collaborative behavior in the laboratory. Student questionnaires (n = 21) and interviews (n = 5), as well as in-class observations, were conducted to examine student perspectives on the laboratory activities. The quantitative and qualitative data were examined using the framework of activity theory to identify contradictions between student expectations of, and engagement with, the activity and the actual experiences of the students. Results indicate that learner-generated photograph and video content can act as a rich source of data on student learning processes and can be used for formative assessment, for observing collaborative behavior, and as a starting point for class discussions. This study stresses the idea that technology choice for activities must align with instructional goals. This research also highlights the utility of activity theory as a framework for assessing classroom and laboratory activities, demonstrating that this approach can guide the development of laboratory activities.

In five experiments, we examined cross-language activation during speech production in various groups of bilinguals and trilinguals who differed in nonnative language proficiency, language learning background, and age. In Experiments 1, 2, 3, and 5, German 5- to 8-year-old second language learners of English, German-English bilinguals, German-English-Language X trilinguals, and adult German-English bilinguals, respectively, named pictures in German and in English; in Experiment 4, 6- to 8-year-old German monolinguals named pictures in German. In both language conditions, cognate status was manipulated. We found that the bidirectional cognate facilitation effect was significant in all groups except the German monolinguals (Experiment 4) and, critically, the child second language learners (Experiment 1) in whom only native language (L1) German had an effect on second language (L2) English. The findings demonstrate how the integration of languages into a child's system follows a developmental path that, at lower levels of proficiency, allows only limited cross-language activation. The results are interpreted against the backdrop of the developing language systems of the children both for early second language learners and for early bi- and trilinguals.

This study researches how first-year engineering students perceived the influence of curricular activities on their own learning autonomy, measured with an adaptation of the Personal Responsibility Orientation to Self-direction in Learning Scale (PRO-SDLS). Participants were questioned to assess the influence of the teacher's role. The results indicate that learners' characteristics (motivation and self-efficacy) contribute more to learner autonomy (LA) than the teaching-learning transaction (control and initiative), as in the original PRO-SDLS validation. The most autonomous learners presented higher values in all LA components and dimensions, but the differences were greater in motivation and initiative. The participants with higher LA were not as dependent on the teacher, regarding assessment, the completion of classroom tasks and deadlines. Regardless of the degree of autonomy in learning, all participants viewed teachers as the main source of information. Therefore, LA plays an important role in teaching activities planning. Suggestions for adjustments and more flexible learning scenarios are formulated.

While teaching in a tutorial, seminar, or problem-based learning group format may be the most fun and most active/interactive for both learner and faculty mentor, there are situations in medical student education in which various constraints require the use of the "lecture" format. Similar constraints may occur in the field of continuing medical education, or graduate medical education, as well. When this occurs, the faculty mentor can increase the active participation of the learners in the audience by continuously stressing seven key pedagogical (androgogical) principles. These include: 1) begin the learning exercise with a clinical example or anecdote to show the relevance of the material to the student; 2) frequently ask the students whether they have ever seen examples of what you describe in their previous experience with patients, personal experience, experience with relatives, etc.; 3) ask students frequently whether they have heard similar material presented differently in other courses; 4) recruit students to help solve "mystery cases"; 5) show examples of similar material from real life (e.g., patient descriptions, or even excerpts from favorite TV shows); 6) ask students to help summarize key points at the end of the session; and 7) allow, or even encourage, whispering during the class. Using some or all of these techniques can help turn a "lecture format" into a much more fun, interactive, and valuable session that emphasizes "learning" rather than "teaching."

This cohort sequential study explored the components of working memory that underlie English reading and language acquisition in elementary school children whose first language is Spanish. To this end, children (N=410) in Grades 1, 2, and 3 at Wave 1 were administered a battery of cognitive (short-term memory [STM], working memory [WM], rapid naming, phonological processing, and random letter and number generation), vocabulary, and reading measures in both Spanish and English. These same measures were administered 1 and 2 years later. The results showed that (a) a three-factor structure (phonological STM, visual-spatial WM, and verbal WM) captured the data within both language systems, (b) growth in both the executive and STM storage components was uniquely related to growth in second language (L2) reading and language acquisition, and (c) the contribution of growth in the executive component of WM to growth in L2 processing was independent of growth in storage, phonological knowledge, inhibition, and rapid naming speed. The results suggested that growth in the phonological storage system does not supersede growth of the executive component of WM as a major contributor to growth in children's L2 reading and language.

Modeling and using technology are two practices of particular interest to K-12 science educators. These practices are inextricably linked among professionals, who engage in modeling activity with and across a variety of representational technologies. In this paper, we explore the practices of five sixth-grade girls as they generated models of smell diffusion using drawing, stop-motion animation, and computational simulation during a multi-day workshop. We analyze video, student discourse, and artifacts to address the questions: In what ways did learners' modeling practices, reasoning about mechanism, and ideas about smell shift as they worked across this variety of representational technologies? And, what supports enabled them to persist and progress in the modeling activity? We found that the girls engaged in two distinct modeling cycles that reflected persistence and deepening engagement in the task. In the first, messing about, they focused on describing and representing many ideas related to the spread of smell at once. In the second, digging in, they focused on testing and revising specific mechanisms that underlie smell diffusion. Upon deeper analysis, we found these cycles were linked to the girls' invention of "oogtom," a representational object that encapsulated many ideas from the first cycle and allowed the girls to restart modeling with the mechanistic focus required to construct simulations. We analyze the role of activity design, facilitation, and technological infrastructure in this pattern of engagement over the course of the workshop and discuss implications for future research, curriculum design, and classroom practice.

The Professional Development Program (PDP) supports participants as they design inquiry activities that help learners improve their research process skills. These skills include the cognitive or reasoning skills that scientists and engineers use while doing research; for example, making a testable hypothesis, coordinating results from multiple experiments, or identifying and evaluating tradeoffs. Past work in the PDP indicated that additional support was needed to help participants design instructional activities that would teach these important skills. A new workshop was therefore developed for the 2009 PDP cycle, entitled "Improving Learners' Process Skills." In this workshop, participants worked in small groups to define specific science and engineering skills found in four past PDP activity designs. Participants distinguished between "simple tasks" and "authentic inquiry" activities that learners could perform as demonstration of the skill. Through this new workshop, participants were able to explicitly discuss ways in which individual process skills are unique or inter-related. In addition, by identifying a "simple task," participants were able to pinpoint areas in which their own designs could be improved to better focus on authentic inquiry tasks. In 2010, the workshop was slightly modified to help participants reconnect the research process skills with the activity content. In addition, the idea of using generic and context-specific scaffolds was also introduced. To make the participants feel like they were contributing to the PDP community, four activity designs actively being worked on in the 2010 cycle were used. Based on participant feedback, this "Improving Learners' Process Skills" workshop should be strongly considered for future returning participants.

Data-driven learning has been proved as an effective approach in helping learners solve various writing problems such as correcting lexical or grammatical errors, improving the use of collocations and generating ideas in writing, etc. This article reports on an empirical study in which data-driven learning was accomplished with the assistance of the user-friendly BNCweb, and presents the evaluation of the outcome by comparing the effectiveness of BNCweb and a search engine Baidu which is most commonly used as reference resource by Chinese learners of English as a foreign language. The quantitative results about 48 Chinese college students revealed that the experimental group which used BNCweb performed significantly better in the post-test in terms of writing fluency and accuracy, as compared with the control group which used the search engine Baidu. However, no significant difference was found between the two groups in terms of writing complexity. The qualitative results about the interview revealed that learners generally showed a positive attitude toward the use of BNCweb but there were still some problems of using corpora in the writing process, thus the combined use of corpora and other types of reference resource was suggested as a possible way to counter the potential barriers for Chinese learners of English.

Although the scientific disciplines conduct practical work in different ways, all consider practical work as the essential way of connecting objects and phenomena with ideas and the abstract. Accordingly, practical work is regarded as central to science education as well. We investigate a practical, object-based palaeontology programme at a natural history museum to identify how palaeontological objects prompt scientific activity among upper secondary school students. We first construct a theoretical framework based on an analysis of the programme's palaeontological content. From this, we build our reference model, which considers the specimens used in the programme, possible palaeontological interpretations of these specimens, and the conditions inherent in the programme. We use the reference model to analyse the activities of programme participants, and illustrate how these activities are palaeontologically authentic. Finally, we discuss our findings, examining the mechanism by which the specimens prompt scientific activities. We also discuss our discipline-based approach, and how it allows us to positively identify participants' activities as authentic. We conclude by discussing the implications of our findings.

A detailed programmatic and technical development plan for active microwave technology was examined in each of four user activities: (1) vegetation; (2) water resources and geologic applications, and (4) oceanographic applications. Major application areas were identified, and the impact of each application area in terms of social and economic gains were evaluated. The present state of knowledge of the applicability of active microwave remote sensing to each application area was summarized and its role relative to other remote sensing devices was examined. The analysis and data acquisition techniques needed to resolve the effects of interference factors were reviewed to establish an operational capability in each application area. Flow charts of accomplished and required activities in each application area that lead to operational capability were structured.

The purpose of this study was to determine whether cross-sectional and growth effects in second language (L2) literacy are related to the executive component of working memory (WM) and whether inhibition may underlie the links between WM and reading in children whose first language (L1) is Spanish. Elementary school children (grades 1, 2 and 3) were administered a battery of cognitive [WM, short-term memory (STM), random generation, rapid naming, phonological processing], vocabulary and reading measures in both Spanish (L1) and English (L2) in Year 1 and again one year later. The regression analyses showed that L2 growth in WM significantly predicted growth in L2 reading skills even when inhibition was controlled. Further, the contributions of WM to reading growth in both L1 and L2 reading were independent of cross-language skills in phonological processing, STM, oral language and naming speed. Overall, the results suggest the mental activities that underlie WM and inhibition in predictions of L2 literacy reflect independent executive processes.

To determine whether the social class differences in duodenal ulcer frequency may be explained by differences in physical activity at work, the energy expenditure during work, smoking habits, and social class were compared in 76 recently diagnosed duodenal ulcer patients and in age and sex matched community controls. As anticipated, the relative risk of duodenal ulcer showed significant associations with smoking and social class. Social class and physical activity at work were associated with one another. After adjusting for age, sex, smoking, and social class, physically active work was still associated with duodenal ulcer, with relative risks for moderate and high activity compared with sedentary work being 1.3 (0.6-3.0) and 3.6 (1.3-7.8) respectively. Within each social class stratum, the relative risk of having a duodenal ulcer was greater in those with a high level of occupational activity than in those undertaking sedentary work. PMID:1916502

In this study, we explored whether the contribution of working memory (WM) to children's (N = 471) 2nd language (L2) reading and language acquisition was best accounted for by processing efficiency at a phonological level and/or by executive processes independent of phonological processing. Elementary school children (Grades 1, 2, & 3) whose…

The effects of increased cardiac work, pyruvate and insulin on the state of pyruvate dehydrogenase (PDH) activation and rate of pyruvate decarboxylation was studied in the isolated perfused rat heart. At low levels of cardiac work, 61% of PDH was present in the active form when glucose was the only substrate provided. The actual rate of pyruvate decarboxylation was only 5% of the available capacity calculated from the percent of active PDH. Under this condition, the rate of pyruvate decarboxylation was restricted by the slow rate of pyruvate production from glycolysis. Increasing cardiac work accelerated glycolysis, but production of pyruvate remained rate limiting for pyruvate oxidation and only 40% of the maximal active PDH capacity was used. Addition of insulin along with glucose reduced the percent of active PDH to 16% of the total at low cardiac work. This effect of insulin was associated with increased mitochondria NADH/NAD and acetyl CoA/CoA ratios. With both glucose and insulin the calculated maximum capacity of active PDH was about the same as measured rates of pyruvate oxidation indicating that pyruvate oxidation was limited by the activation state of PDH. In this case, raising the level of cardiac work increased the active PDH to 85% and although pyruvate oxidation was accelerated, measured flux through PDH was only 73% of the maximal activity of active PDH. With pyruvate as added exogenous substrate, PDH was 82% of active at low cardiac work probably due to pyruvate inhibition of PDH kinase. In this case, the measured rate of pyruvate oxidation was 64% of the capacity of active PDH. However, increased cardiac work still caused further activation of PDH to 96% active. Thus, actual rates of pyruvate oxidation in the intact tissue were determined by (1) the supply of pyruvate in hearts receiving glucose alone, (2) by the percent of active PDH in hearts receiving both glucose and insulin at low work and (3) by end-product inhibition in hearts receiving

If the market has an invisible hand, does knowledge creation and representation have an “invisible brain”? While knowledge is viewed as a product of neuron activity in the brain, can we identify knowledge that is outside the brain but reflects the activity of neurons in the brain? This work suggests that the patterns of neuron activity in the brain can be seen in the representation of knowledge-related activity. Here we show that the neuron activity mechanism seems to represent much of the knowledge learned in the past decades based on published articles, in what can be viewed as an “invisible brain” or collective hidden neural networks. Similar results appear when analyzing knowledge activity in patents. Our work also tries to characterize knowledge increase as neuron network activity growth. The results propose that knowledge-related activity can be seen outside of the neuron activity mechanism. Consequently, knowledge might exist as an independent mechanism. PMID:27439199

The prefrontal cortex is activated during working memory, as evidenced by fMRI results in human studies and neurophysiological recordings in animal models. Persistent activity during the delay period of working memory tasks, after the offset of stimuli that subjects are required to remember, has traditionally been thought of as the neural correlate of working memory. In the last few years several findings have cast doubt on the role of this activity. By some accounts, activity in other brain areas, such as the primary visual and posterior parietal cortex, is a better predictor of information maintained in visual working memory and working memory performance; dynamic patterns of activity may convey information without requiring persistent activity at all; and prefrontal neurons may be ill-suited to represent non-spatial information about the features and identity of remembered stimuli. Alternative interpretations about the role of the prefrontal cortex have thus been suggested, such as that it provides a top-down control of information represented in other brain areas, rather than maintaining a working memory trace itself. Here we review evidence for and against the role of prefrontal persistent activity, with a focus on visual neurophysiology. We show that persistent activity predicts behavioral parameters precisely in working memory tasks. We illustrate that prefrontal cortex represents features of stimuli other than their spatial location, and that this information is largely absent from early cortical areas during working memory. We examine memory models not dependent on persistent activity, and conclude that each of those models could mediate only a limited range of memory-dependent behaviors. We review activity decoded from brain areas other than the prefrontal cortex during working memory and demonstrate that these areas alone cannot mediate working memory maintenance, particularly in the presence of distractors. We finally discuss the discrepancy between

Mothers' work hours are likely to affect their time allocation towards activities related to children's diet, activity and well-being. For example, mothers who work more may be more reliant on processed foods, foods prepared away from home and school meal programs for their children's meals. A greater number of work hours may also lead to more unsupervised time for children that may, in turn, allow for an increase in unhealthy behaviors among their children such as snacking and sedentary activities such as TV watching. Using data on a national cohort of children, we examine the relationship between mothers' average weekly work hours during their children's school years on children's dietary and activity behaviors, BMI and obesity in 5th and 8th grade. Our results are consistent with findings from the literature that maternal work hours are positively associated with children's BMI and obesity especially among children with higher socioeconomic status. Unlike previous papers, our detailed data on children's behaviors allow us to speak directly to affected behaviors that may contribute to the increased BMI. We show that children whose mothers work more consume more unhealthy foods (e.g. soda, fast food) and less healthy foods (e.g. fruits, vegetables, milk) and watch more television. Although they report being slightly more physically active, likely due to organized physical activities, the BMI and obesity results suggest that the deterioration in diet and increase in sedentary behaviors dominate.

The effect of three types of physical activity on two types of working memory were investigated. Participants were 20 adult males who trained twice a week in volleyball two hours per session. Procedures included two pre and post intervention tests of working memory: the Digit span and Visual Memory Span subtests of the Wechsler Memory Scale-Revised. Interventions included tactical volleyball formation, body-weight resistance exercises, 15 minutes of running, and sub-maximal aerobic activity. Volleyball activity improved memory performance to a greater extent than the other two activities. Results indicate that immediately after acute exercise there is an increase in working memory function, more evident after physical activity in which cognitive functioning is inherent.

A work domain analysis (WDA) of human extravehicular activity (EVA) is presented in this study. A formative methodology such as Cognitive Work Analysis (CWA) offers a new perspective to the knowledge gained from the past 50 years of living and working in space for the development of future EVA support systems. EVA is a vital component of human spaceflight and provides a case study example of applying a work domain analysis (WDA) to a complex sociotechnical system. The WDA presented here illustrates how the physical characteristics of the environment, hardware, and life support systems of the domain guide the potential avenues and functional needs of future EVA decision support system development.

This study explored the relationship between cultural leisure activities, recovery experiences and two outcomes among hospital workers. The differences in recovery experiences (detachment, relaxation, mastery and control) and outcomes (work engagement and subjective recovery state) among hospital personnel (N=769) were analysed by the type (receptive or creative) and frequency of cultural activities. The cross-sectional data were collected by a digital questionnaire. Employees who reported both receptive and creative cultural leisure activities on a weekly basis had the highest relaxation, mastery and control experiences during off-job time. In addition, those with weekly creative activities had beneficial mastery experiences. There were no differences in recovery outcomes after adjustment for age, except in work engagement. Cultural leisure activities, and creative activities in particular, play an important role in certain aspects of recovery.

There is extensive evidence that the contralateral delay activity (CDA), a scalp recorded event-related brain potential, provides a reliable index of the number of objects held in visual working memory. Here we present evidence that the CDA not only indexes visual object working memory, but also the number of locations held in spatial working memory. In addition, we demonstrate that the CDA can be predictably modulated by the type of encoding strategy employed. When individual locations were held in working memory, the pattern of CDA modulation mimicked previous findings for visual object working memory. Specifically, CDA amplitude increased monotonically until working memory capacity was reached. However, when participants were instructed to group individual locations to form a constellation, the CDA was prolonged and reached an asymptote at two locations. This result provides neural evidence for the formation of a unitary representation of multiple spatial locations.
In the description of my work I presented my own experience in the organizing and carrying out of extracurricular activities with the students, the used modes and methods of work, the obtained results and some good practices in the field of natural sciences. Organizing and carrying out of scientific festivals, participation in joint projects together with scientific organizations. Key words: European dimension, interactive methods, key competences, natural sciences, extracurricular activities. We are witnesses of a fundamental change in the pedagogical culture and practice in our schools to establish the parameters of the quality of training. The good scientific culture is an important part of the students' education. Unfortunately, at the present time the scientific and technological culture is on a low level. One of the contemporary problems and realities of the education in natural science school subjects, as a whole and in particular in the secondary education, is the decreased interest for the training in them and in particular in physics, as well as synchronization of the interrelations: school environment - society. In many countries there is a drop in the orientation of the students towards the science and technology - the problem of Science and Technology (S&T). The training of the young people often creates some problems. The teachers meet with the problem of insufficient motivation of the learners for study and difficulties that they encounter in the process of training. The students find it difficult to apply the mastered knowledge to an applied context. The knowledge is rather academic and rather remote from the context, in which the children live and communicate, which makes it nonfunctional. At present there are not enough extracurricular activities that should meet these necessities of the Bulgarian school. The reasons are various, but they mainly consist in the lack of a material base, an exchange of experience and good practices and motivation

Language proficiency is a key to academic and workplace success for native and non-native speakers. It is largely unknown, however, why some people pick up languages more easily than others. We used event-related functional magnetic resonance imaging (e-fMRI) to elucidate which brain regions are modulated during the acquisition of a novel lexicon and which of these learning-related activity changes correlated with general semantic language knowledge. Fourteen healthy young subjects learned a novel vocabulary of 45 concrete nouns via an associative learning principle over the course of five blocks during e-fMRI. As a control condition, subjects took part in a structurally identical "No-Learning" condition lacking any learning principle. Overall, increasing vocabulary proficiency was associated with (intercorrelated) modulations of activity within the left hippocampus and the left fusiform gyrus, regions involved in the binding and integration of multimodal stimuli, and with an increasing activation of the left inferior parietal cortex, the presumed neural store of phonological associations. None of these activity changes were observed during the control condition. Furthermore, subjects who showed less suppression of hippocampal activity over learning blocks scored higher on semantic knowledge in their native language and learned the novel vocabulary more efficiently. Our findings indicate that (a) the successful acquisition of a new lexicon depends on correlated amplitude changes between the left hippocampus and neocortical regions and (b) learning-related hippocampus activity is a stable marker of individual differences in the ability to acquire and master vocabularies.

Work in confined spaces poses a significant risk to workers and rescuers involved in the emergency response when an accident occurs. Despite several standards and regulations define the safety requirements for such activities, injuries, and fatalities still occur. Furthermore, the on-site inspections after accidents often reveal that both employers and employees fail to implement safe entry procedures. Removing the risk is possible by avoiding the worker entry, but many activities require the presence of the operator inside the confined space to perform manual tasks. The following study investigates the available technologies for hazardous confined space work activities, e.g., cleaning, inspecting, and maintenance tasks. The aim is to provide a systematic review of the automated solutions for high-risk activities in confined spaces, considering the non-man entry as the most effective confined space safety strategy. Second, this survey aims to provide suggestions for future research addressing the design of new technologies. The survey consists of about 60 papers concerning innovative technologies for confined space work activities. The document review shows that several solutions have been developed and automation can replace the workers for a limited number of hazardous tasks. Several activities still require the manual intervention due to the complex characteristics of confined spaces, e.g., to remove the remains of the automatic cleaning process from the bottom of a tank. The results show that available technologies require more flexibility to adapt to such occupational environments and further research is needed.

We conducted a 12-month-long experiment in a financial services company to study how the availability of treadmill workstations affects employees' physical activity and work performance. We enlisted sedentary volunteers, half of whom received treadmill workstations during the first two months of the study and the rest in the seventh month of the study. Participants could operate the treadmills at speeds of 0-2 mph and could use a standard chair-desk arrangement at will. (a) Weekly online performance surveys were administered to participants and their supervisors, as well as to all other sedentary employees and their supervisors. Using within-person statistical analyses, we find that overall work performance, quality and quantity of performance, and interactions with coworkers improved as a result of adoption of treadmill workstations. (b) Participants were outfitted with accelerometers at the start of the study. We find that daily total physical activity increased as a result of the adoption of treadmill workstations.

Working memory (WM) capacity measured through complex span tasks is among the best predictors of fluid intelligence (Gf). These tasks usually involve maintaining memoranda while performing complex cognitive activities that require a rather high level of education (e.g., reading comprehension, arithmetic), restricting their range of applicability. Because individual differences in such complex activities are nothing more than the concatenation of small differences in their elementary constituents, complex span tasks involving elementary processes should be as good of predictors of Gf as traditional tasks. The present study showed that two latent variables issued from either traditional or new span tasks involving time-constrained elementary activities were similarly correlated with Gf. Moreover, a model with a single unitary WM factor had a similar fit as a model with two distinct WM factors. Thus, time-constrained elementary activities can be integrated in WM tasks, permitting the assessment of WM in a wider range of populations.

OBJECTIVES: To determine the prevalence and risk factors for work related musculoskeletal disorders among union carpenters. METHODS: A detailed questionnaire on musculoskeletal symptoms and work history was administered to 522 carpenters. The symptom questions assessed if carpenters experienced pain, numbness, or tingling in a particular body region. A subset of this group then received a physical examination of the upper extremities and knees. RESULTS: The study group was primarily white (94.9%) and male (97.8%) with a mean age of 42.3 years. The highest prevalence of work related musculoskeletal disorders cases by carpentry specialty ranged from 20%-24% for those doing drywall or ceiling, finishing or framing, and the building of concrete forms. Generally, as duration of employment increased, the prevalence of symptoms increased. An adjusted logistic regression analysis showed that the group with the longest (> or = 20 years) duration of employment in carpentry was significantly associated with work related musculoskeletal disorders of the shoulders (odds ratio (OR) 3.2, 95% confidence interval (95% CI) 1.1 to 8.9), hands or wrists (OR 3.1, 95% CI 1.1 to 8.4), and knees (OR 3.5, 95% CI 1.3 to 9.2). Also, analyses showed that carpenters who reported that they had little or no influence over their work schedule had significant increases of work related musculoskeletal disorders of the shoulders, hips, and knees with ORs of 1.9 (95% CI 1.1 to 3.2), 2.9 (95% CI 1.1 to 7.2), and 2.3 (95% CI 1.2 to 4.1), respectively. Feeling exhausted at the end of day was also a significant risk factor for work related musculoskeletal disorders of the knee (OR 1.8, 95% CI 1.1 to 3.1). Upper extremity disorders were the most prevalent work related musculoskeletal disorders reported among all carpenters. Drywall or ceiling activities involve a considerable amount of repetitive motion and awkward postures often with arms raised holding heavy dry walls in place, whereas form work is

Previous studies have shown that working memory (WM) processes are related to frontal-midline theta (FM-theta) activity (4-8 Hz) and test anxiety impairs WM performance. However, the effect of test anxiety on FM-theta activity during WM has not been investigated as yet. To examine this question, 37 undergraduates were asked to complete a modified reading span task involving neutral working memory capacity (WMC) and emotional WMC while their electroencephalography was measured. The results showed that relative to neutral WMC performance (the ability to remember the letter lists in the context of valence-neutral sentences), emotional WMC performance (the ability to remember the letter lists in the context of test-related sentences) was poorer for highly test anxious participants compared with lowly test anxious participants. Relative to FM-theta activity during remembering the letter lists in the valence-neutral context, FM-theta activity was weaker during remembering the letter lists in the test-related context for highly test anxious participants compared with lowly test anxious participants. These findings indicate that FM-theta is an index not only for successful WM manipulation but also for efficient prefrontal cortex functioning during WM.

Working memory (WM) maintenance is assumed to rely on a single sustained process throughout the entire maintenance period. This assumption, although fundamental, has never been tested. We used intracranial electroencephalography (EEG) recordings from the human hippocampus in two independent experiments to investigate the neural dynamics underlying WM maintenance. We observed periodic fluctuations between two different oscillatory regimes: Periods of "memory activation" were reflected by load-dependent alpha power reductions and lower levels of cross-frequency coupling (CFC). They occurred interleaved with periods characterized by load-independent high levels of alpha power and CFC. During memory activation periods, a relevant CFC parameter (load-dependent changes of the peak modulated frequency) correlated with individual WM capacity. Fluctuations between these two periods predicted successful performance and were locked to the phase of endogenous delta oscillations. These results show that hippocampal maintenance is a dynamic rather than constant process and depends critically on a hierarchy of oscillations.
The starting point for curriculum planning for second language instruction is the learner, and a curriculum can claim to be learner-centered only if key factors about the learner are made the basis for curriculum design at all stages in the planning and development of learning activities and materials and in the sequencing of learning experiences.…

Computer users are often under stress when required to complete computer work within a required time. Work stress has repeatedly been associated with an increased risk for cardiovascular disease. The present study examined the effects of time pressure workload during computer tasks on cardiac activity in 20 healthy subjects. Heart rate, time domain and frequency domain indices of heart rate variability (HRV) and Poincaré plot parameters were compared among five computer tasks and two rest periods. Faster heart rate and decreased standard deviation of R-R interval were noted in response to computer tasks under time pressure. The Poincaré plot parameters showed significant differences between different levels of time pressure workload during computer tasks, and between computer tasks and the rest periods. In contrast, no significant differences were identified for the frequency domain indices of HRV. The results suggest that the quantitative Poincaré plot analysis used in this study was able to reveal the intrinsic nonlinear nature of the autonomically regulated cardiac rhythm. Specifically, heightened vagal tone occurred during the relaxation computer tasks without time pressure. In contrast, the stressful computer tasks with added time pressure stimulated cardiac sympathetic activity.

Massively open online courses (MOOCs) are becoming increasingly popular ways to reach diverse lifelong learners all over the world. Although MOOCs resemble more formal classes (e.g. videos of content, quizzes, activities), they are often used by informal audiences from home. Recently, MOOCs have become more utilized by universities to conduct outreach as they explore how to use MOOCs to reach new potential learners. Despite the rapid adaption of MOOCs, little is known about individuals who choose to take a MOOC, how they interact with the course materials, and what motivates them to finish the course.We present results of a study of lifelong learners engaged in an astronomy "101" MOOC. Through analysis of registered learners' behaviors as well as self-reported responses to a survey about science, we were able to characterize a subset of the learners engaged in the MOOC during its first offering. Overall, 25363 learners from over 100 countries registered for the MOOC. Of those, 14900 accessed at least one part of the course. Learners were recruited to complete a survey of their knowledge and attitudes towards science. Of the learner group who opened the course, 2889 individuals completed the survey, 2465 of those were able to be linked to their usage of the MOOC through a unique identifier.Learners represented a wide-range of ages, professions, and previous science experience. The best predictors for MOOC completion were engagement in the first activity and first writing assignment and engagement in the online forum. Learners were very interested in science prior to their registration, had higher basic science knowledge that most undergraduate students enrolled in a parallel astronomy course, and used online searches and science sites to get their information about science. As we reach out to a worldwide audience to learners in these massively open online courses, understanding their motivations and behaviors will be essential. This work is helping us understand and

Farmwomen are often an unacknowledged workforce, leading to a lack of targeted safety interventions. This study examined the involvement and work patterns of 665 women in Texas and 657 women in Louisiana who were 18 years old and older and whose family participated in farming operations. Surveys were used to gather specific data regarding tractor work patterns, tractor knowledge, sources of information about tractors, and demographic information in two southern states in which cattle and dairy were the major agricultural commodity. Among the sample of 1,322 women, 577 (43.6%) reported driving tractors at least one day a year. This subset was used to describe characteristics of tractors and tractor-related activities. Findings indicate that women learn to drive tractors in their 20s, use husbands as the primary source of their information about tractors, engage in a wide variety of farm activities including bush-hogging and plowing, and acknowledge knowing an average or less than an average amount about driving tractors. Women most often reported driving between 1 to 12 days/year (n = 321, 55.6%). When examining patterns of ROPS-equipped tractor use, women were 1.47 times more likely to drive a tractor without ROPS or enclosed when driving less than 12 days a year as opposed to 13-103 days/year or greater than 104 days/year. The results of this study support the need for health care professionals and safety specialists to design appropriate interventions that target women to become more knowledgeable regarding the injury risks associated with farm work while driving tractors.

The conceptual notion of the so-called resting state of the brain has been recently challenged by studies indicating a continuing effect of cognitive processes on subsequent rest. In particular, activity in posterior parietal and medial prefrontal areas has been found to be modulated by preceding experimental conditions. In this study, we investigated which brain areas show working memory dependent patterns in subsequent baseline periods and how specific they are for the preceding experimental condition. During functional magnetic resonance imaging, 94 subjects performed a letter-version of the n-back task with the conditions 0-back and 2-back followed by a low-level baseline in which subjects had to passively observe the letters appearing. In a univariate analysis, 2-back served as control condition while 0-back, baseline after 0-back and baseline after 2-back were modeled as regressors to test for activity changes between both baseline conditions. Additionally, we tested, using Gaussian process classifiers, the recognition of task condition from functional images acquired during baseline. Besides the expected activity changes in the precuneus and medial prefrontal cortex, we found differential activity in the thalamus, putamen, and postcentral gyrus that were affected by the preceding task. The multivariate analysis revealed that images of the subsequent baseline block contain task related patterns that yield a recognition rate of 70%. The results suggest that the influence of a cognitive task on subsequent baseline is strong and specific for some areas but not restricted to areas of the so-called default mode network.

Nurses report a high prevalence of musculoskeletal discomfort, particularly of the low back and neck/shoulder. This study characterized the full-shift upper arm and trunk postures and movement velocities of registered nurses using inertial measurement units (IMUs). Intensity of occupational physical activity (PA) was also ascertained using a waist-worn PA monitor and using the raw acceleration data from each IMU. Results indicated that nurses spent a relatively small proportion of their work time with the arms or trunk in extreme postures, but had few opportunities for rest and recovery in comparison to several other occupational groups. Comparisons between nurses in different PA groups suggested that using a combination of accelerometers secured to several body locations may provide more representative estimates of physical demands than a single, waist-worn PA monitor. The findings indicate a need for continued field-based research with larger sample sizes to facilitate the development of maximally effective intervention strategies.

We review here the progress of the Variability of the American MOnsoon Systems (VAMOS) extremes working group since it was formed in February of 2010. The goals of the working group are to 1) develop an atlas of warm-season extremes over the Americas, 2) evaluate existing and planned simulations, and 3) suggest new model runs to address mechanisms and predictability of extremes. Substantial progress has been made in the development of an extremes atlas based on gridded observations and several reanalysis products including Modern Era Retrospective-Analysis for Research and Applications (MERRA) and Climate Forecast System Reanalysis (CFSR). The status of the atlas, remaining issues and plans for its expansion to include model data will be discussed. This includes the possibility of adding a companion atlas based on station observations based on the software developed under the World Climate Research Programme (WCRP) Expert Team on Climate Change. Detection and Indices (ETCCDI) activity. We will also review progress on relevant research and plans for the use and validation of the atlas results.

Brief abstinence from smoking impairs cognition, particularly executive function, and this has a role in relapse to smoking. This study examined whether working memory-related brain activity predicts subsequent smoking relapse above and beyond standard clinical and behavioral measures. Eighty treatment-seeking smokers completed two functional magnetic resonance imaging sessions (smoking satiety vs 24 h abstinence challenge) during performance of a visual N-back task. Brief counseling and a short-term quit attempt followed. Relapse during the first 7 days was biochemically confirmed by the presence of the nicotine metabolite cotinine. Mean percent blood oxygen level-dependent (BOLD) signal change was extracted from a priori regions of interest: bilateral dorsolateral prefrontal cortex (DLPFC), medial frontal/cingulate gyrus, posterior cingulate cortex (PCC), and ventromedial prefrontal cortex. Signal from these brain regions and additional clinical measures were used to model outcome status, which was then validated with resampling techniques. Relapse to smoking was predicted by increased withdrawal symptoms, decreased left DLPFC and increased PCC BOLD percent signal change (abstinence vs smoking satiety). Receiver operating characteristic analysis demonstrated 81% area under the curve using these predictors, a significant improvement over the model with clinical variables only. The combination of abstinence-induced decreases in left DLPFC activation and reduced suppression of PCC may be a prognostic marker for poor outcome, specifically early smoking relapse. PMID:25469682

We describe learners enrolled in three iterations of introductory astronomy massive open online courses (MOOCs). These courses are offered through commercial providers and facilitated by an instructional team at the University of Arizona. We describe an ongoing study of those who enroll, engage in, and complete these courses. The course has undergone several revisions, including integrating pedagogical techniques, found to be effective for in-person courses, to increase engagement including peer review, online discussions, and the use of cohorts. In its current version, learners enroll on a continual basis and complete 11 weeks of course content; they watch videos, complete content quizzes, submit writing assignments, complete peer review of other students’ work, and complete online citizen science projects. Tens of thousands of students has signed up for these courses but completion rates are much lower, around 10%. We have collected survey data from over 8,500 of these learners to assess their basic science knowledge, attitudes towards science and technology, motivations for taking the courses, and information about other ways they engage in science related activities. We present information about these learners, including their demographics, motivations, how they use the courses, and what factors lead to increased engagement and completion. Additionally, we present how survey data from these learners compare to 26 years of data we have collected from parallel group of undergraduate non-science major students enrolled in astronomy courses at the University of Arizona. Overall, we find that learners who enroll in the MOOCs have more interest in science and higher basic science knowledge that undergraduates who pay tuition for a similar course. Our work is helping us understand how to better serve learners in MOOCs and bridge more traditional courses with these types of courses.

Little is currently known about the physical activity patterns of workers in physically demanding populations. The aims of this study were to (a) quantify firefighters’ physical activity and sedentary time within (2-h periods) and across planned burn shifts; and (b) examine whether firefighters’ activity levels during one shift or 2-h period was associated with their activity levels in the following shift or 2-h period. Thirty-four salaried firefighters (26 men, 8 women) wore an Actical accelerometer for 28 consecutive days. Time spent sedentary (SED) and in light- (LPA), moderate- (MPA) and vigorous-intensity physical activity (VPA) were derived using validated cut-points. Multilevel analyses (shift, participant) were conducted using generalised linear latent and mixed models. Firefighters spent the majority of a planned burn shift (average length 10.4 h) or 2-h period engaged in LPA (69% and 70%, respectively). No significant associations were observed between SED and physical activity levels between consecutive planned burned shifts or 2-h periods. The physical activity that a firefighter engaged in during one shift (or 2-h period) did not subsequently affect their physical activity levels in the subsequent shift (or 2-h period). Further research is needed to establish how workers in physically demanding populations are able to sustain their activity levels over long periods of time. PMID:27706057

Work activity and health symptoms of bank tellers whose work was undergoing reorganization were examined during a university-union study of the health effects of work in women's traditional jobs. Data were gathered through collective and individual interviews, analysis of work activity, and a questionnaire administered to 305 tellers. Employees worked in a standing posture over 80 percent of the time. More than two-thirds frequently suffered pain in back, legs, and feet. The average teller had been involved in 3.7 robberies as a direct victim and six as a witness. Work required feats of memory and concentration. In order to meet job demands, tellers engaged in supportive activities and teamwork. The introduction of individualized objectives threatened the employees' ability to collaborate and induced distress. More than twice as many tellers as other female workers in Québec experience psychological distress (Ilfeld scale), related to: robbery during the past two years (odds ratio = 1.7; confidence interval = 1.0-2.9); difficult relations with superiors (O.R. = 2.6; C.I. = 1.3-5.3); and full-time work (O.R. = 2.3; C.I. = 1.3-3.9). Diverse methods enriched the analysis, and union participation allowed the proposal of concrete correction measures.

The purpose of this study was to examine the interactions of eighth grade English Language Learners in an inclusive science classroom. There is a paucity of research in this area. Central to this study was the students' perceptions and interactions with five different science curriculum features; teacher presentation and guided notes, worksheets, homework, labs, and practice and review activities. The student participants were English Language Learners from two language proficiency levels and the teacher was a provisionally licensed first year science teacher. The aggregate data included individual interviews with the students and teacher, classroom observations, and the collection of classroom artifacts. The findings revealed: (a) students' comprehension of the material was inconsistent throughout all of the curriculum features and differences were observed not only between but also within the two proficiency levels; (b) classroom organizational issues created challenges for both the teacher and the students; (c) off task behavior was most prevalent during the teacher's one-to-one instruction and interfered with learning; (d) differences between levels of language proficiency were observed among students who preferred to work independently and were comfortable asking the teacher for assistance and the students who preferred working with and receiving assistance from peers; and (e) language proficiency rather than cultural differences appeared to be the greatest barrier to classroom success. Overall, English language proficiency was a crucial determinant in the English Language Learners success in the inclusive classroom. Additionally, implications suggest that a limited teaching skill set could adversely affect the success of students in inclusive classrooms.

Historically, nursing students have questioned the value of a nursing research course and have not appreciated the research-practice link. These are important concerns in light of the increasing emphasis on evidence-based nursing practice. The purpose of this study was to develop innovative strategies for teaching undergraduate nursing research that engage millennial learners and emphasize the relationship between evidence-based practice and clinical outcomes. Innovative assignments were developed that included interactive learning, group work, and practical applications preferred by these learners. Using a Likert scale, students' perceived effectiveness of innovative assignments and more traditional assignments were compared. Results indicated a preference for active learning assignments, reading quizzes, clinical nurse researcher presentations, and collaboration with clinical course assignments. By combining traditional assignments with innovative strategies and nursing practice applications, millennial learners were engaged and able to clearly articulate the value of the research-practice link vital to evidence-based nursing practice.

Education is a cornerstone of antimicrobial stewardships programs, because 50% of inappropriate antimicrobial prescriptions are a consequence of an imbalance between the high levels of knowledge required for the appropriate use of antibiotics and the scarce training offered to medical specialists. For this reason, programs optimizing antimicrobial (PROA) are essentially based on support and educational activities for prescribers. The educational activities are difficult to evaluate. In our country, the application of educational activities in antimicrobial training programs is very heterogeneous, although it has improved in recent years. We recommend the following educational measures, which are prioritized in order of effectiveness. Interactive educational interventions are the most effective. These are non-compulsory interventions based on real prescriptions in clinical practice and include educational outreach visits, audits and counseling interviews with feedback and multifaceted interventions. Passive educational strategies, with posters, newsletters, and dissemination of guidelines, are only marginally effective in changing antimicrobial prescribing practices and have not shown a sustained effect. These measures need extensive professional involvement and should be combined with more active approaches. Currently, interventions can be enhanced with some teaching tools in electronic format. Both interactive and passive educational measures should be integrated into the PROA and should have institutional support. Finally, we recommend including antimicrobials in the training plans of all clinical specialties.

Although there is a trend in today's organisations to implement activity-based flexible offices (A-FOs), only a few studies examine consequences of this new office type. Moreover, the underlying mechanisms why A-FOs might lead to different consequences as compared to cellular and open-plan offices are still unclear. This paper introduces a theoretical framework explaining benefits and risks of A-FOs based on theories from work and organisational psychology. After deriving working conditions specific for A-FOs (territoriality, autonomy, privacy, proximity and visibility), differences in working conditions between A-FOs and alternative office types are proposed. Further, we suggest how these differences in working conditions might affect work-related consequences such as well-being, satisfaction, motivation and performance on the individual, the team and the organisational level. Finally, we consider task-related (e.g. task variety), person-related (e.g. personality) and organisational (e.g. leadership) moderators. Based on this model, future research directions as well as practical implications are discussed. Practitioner Summary: Activity-based flexible offices (A-FOs) are popular in today's organisations. This article presents a theoretical model explaining why and when working in an A-FO evokes benefits and risks for individuals, teams and organisations. According to the model, A-FOs are beneficial when management encourages employees to use the environment appropriately and supports teams.

Working memory (WM) processes depend on our momentary mental state and therefore exhibit considerable fluctuations. Here, we investigate the interplay of task-preparatory and task-related brain activity as represented by pre-stimulus BOLD-fluctuations and spectral EEG from the retention periods of a visual WM task. Visual WM is used to maintain sensory information in the brain enabling the performance of cognitive operations and is associated with mental health. We tested 22 subjects simultaneously with EEG and fMRI while performing a visuo-verbal Sternberg task with two different loads, allowing for the temporal separation of preparation, encoding, retention and retrieval periods. Four temporally coherent networks (TCNs)-the default mode network (DMN), the dorsal attention, the right and the left WM network-were extracted from the continuous BOLD data by means of a group ICA. Subsequently, the modulatory effect of these networks' pre-stimulus activation upon retention-related EEG activity in the theta, alpha, and beta frequencies was analyzed. The obtained results are informative in the context of state-dependent information processing. We were able to replicate two well-known load-dependent effects: the frontal-midline theta increase during the task and the decrease of pre-stimulus DMN activity. As our main finding, these two measures seem to depend on each other as the significant negative correlations at frontal-midline channels suggested. Thus, suppressed pre-stimulus DMN levels facilitated later task related frontal midline theta increases. In general, based on previous findings that neuronal coupling in different frequency bands may underlie distinct functions in WM retention, our results suggest that processes reflected by spectral oscillations during retention seem not only to be "online" synchronized with activity in different attention-related networks but are also modulated by activity in these networks during preparation intervals.
Negotiation of language form is thought to engage learning processes by helping learners to notice gaps in their developing L2 and find target-like ways of filling them. Self-transcription, where learners work together to find language errors in recordings of their own oral output, is an awareness raising exercise that encourages such negotiation.…

The implementation of activity-based funding (ABF) in mental health from 1 July 2013 has significant risks and benefits. It is critical that the process of implementation is consistent with Australia's cherished goal of establishing a genuine and effective model of community-based mental health care. The infrastructure to support the application of ABF to mental health is currently weak and requires considerable development. States and territories are struggling to meet existing demand for largely hospital-based acute mental health care. There is a risk that valuable ABF-driven Commonwealth growth funds may be used to prop up these systems rather than drive the emergence of new models of community-based care. Some of these new models exist now and this article provides a short description. The aim is to help the Independent Hospital Pricing Authority better understand the landscape of mental health into which it now seeks to deploy ABF.

The patterns and magnitudes of past climate change in the topics are still under discussion. We contribute here by reporting on patterns of glacier length changes of the largest glacier in the tropics, Quelccaya Ice Cap (~13.9°S, 70.9°W, summit at 5645 m). This ice cap has several local domes that may have different patterns of length changes because of differing elevations of the domes (high to the north, lower to the south). Prior work (Mark et al. 2003, Abbott et al., 2004; Thompson et al., 2005; Buffen, et al., 2009), new radiocarbon ages, and stratigraphic and geomorphic relationships are used to determine the general pattern of length changes for the outlets from this ice cap. We exploit geomorphic relationships and present new radiocarbon ages on interpreted stratigraphic sections to determine the pattern of length changes for this ice cap. Ice retreated during late glacial times (Rodbell and Seltzer, 2000; Kelly et al., in press). By 11,400 yr BP it had reached a position ~1.2 km beyond its present (2000 AD) extent. While length during the early Holocene is problematic, present evidence permits, but does not prove, extents of 0.5 to 1.0 km down-valley from the present margin. Between 6400 and 4400 yr BP the ice cap was smaller than present, but it advanced multiple times during the late Holocene. Lengths of up to 1 km beyond present were achieved at 3400 yr BP and ~500 yr BP. Additionally, the ice advanced to 0.8 km beyond its present margin at 1600 yr BP. Because these glaciers were temperate, we take these lengths to represent primarily changes in temperature. This may suggest that lowering insolation values in the northern hemisphere during the Holocene provide a first order control on tropical temperatures. Alternatively, it may be that major reorganization of the topical circulation belts about 5000 yr BP yields two configurations of the QIC and hence Holocene temperatures - one at the present ice margin and and the second about 1 km beyond the

Previous studies show that verbal short-term memory (VSTM) is related to vocabulary learning, whereas verbal working memory (VWM) is related to grammar learning in children learning a second language (L2) in the classroom. In this study, we investigated whether the same relationships apply to children learning an L2 in a naturalistic setting and to monolingual children. We also investigated whether relationships with verbal memory differ depending on the type of grammar skill investigated (i.e., morphology vs. syntax). Participants were 63 Turkish children who learned Dutch as an L2 and 45 Dutch monolingual children (mean age = 5 years). Children completed a series of VSTM and VWM tasks, a Dutch vocabulary task, and a Dutch grammar task. A confirmatory factor analysis showed that VSTM and VWM represented two separate latent factors in both groups. Structural equation modeling showed that VSTM, treated as a latent factor, significantly predicted vocabulary and grammar. VWM, treated as a latent factor, predicted only grammar. Both memory factors were significantly related to the acquisition of morphology and syntax. There were no differences between the two groups. These results show that (a) VSTM and VWM are differentially associated with language learning and (b) the same memory mechanisms are employed for learning vocabulary and grammar in L1 children and in L2 children who learn their L2 naturalistically.

The purposes of this study are threefold: 1) to find out what characteristics are required for the successful use of ePortfolios; 2) to discover what activities best represent reflective thinking during the use of ePortfolios; and, 3) to investigate the interrelationship between nursing staff users' perceived success levels with ePortfolios and with their reflective thinking activities. Survey methodology was used to gather responses from 78 nurses from a medical center located in southern Taiwan via questionnaires. Factor analysis and canonical correlation analysis were used to analyze the collected data. The results demonstrated that system quality, information quality, and user satisfaction are important variables in successful ePortfolio usage; while habitual action, understanding, reflection, and critical reflection are major variables of reflective thinking. Further, we found a significant relationship exists between the relative success of ePortfolios and reflective thinking activities of ePortfolios users. The subject hospital should pay special attention to important characteristics including system quality, information quality, and user satisfaction when employing ePortfolios to help nursing staff users to achieve their learning goals through this form of reflective thinking.

Persistent neural activity is a putative mechanism for the maintenance of working memories. Persistent activity relies on the activity of a distributed network of areas, but the differential contribution of each area remains unclear. We recorded single neurons in the human medial frontal cortex and medial temporal lobe while subjects held up to three items in memory. We found persistently active neurons in both areas. Persistent activity of hippocampal and amygdala neurons was stimulus-specific, formed stable attractors and was predictive of memory content. Medial frontal cortex persistent activity, on the other hand, was modulated by memory load and task set but was not stimulus-specific. Trial-by-trial variability in persistent activity in both areas was related to memory strength, because it predicted the speed and accuracy by which stimuli were remembered. This work reveals, in humans, direct evidence for a distributed network of persistently active neurons supporting working memory maintenance.

Motor activity possesses a multiscale regulation that is characterized by fractal activity fluctuations with similar structure across a wide range of timescales spanning minutes to hours. Fractal activity patterns are disturbed in animals after ablating the master circadian pacemaker (suprachiasmatic nucleus, SCN) and in humans with SCN dysfunction as occurs with aging and in dementia, suggesting the crucial role of the circadian system in the multiscale activity regulation. We hypothesized that the normal synchronization between behavioural cycles and the SCN-generated circadian rhythms is required for multiscale activity regulation. To test the hypothesis, we studied activity fluctuations of rats in a simulated shift work protocol that was designed to force animals to be active during the habitual resting phase of the circadian/daily cycle. We found that these animals had gradually decreased mean activity level and reduced 24-h activity rhythm amplitude, indicating disturbed circadian and behavioural cycles. Moreover, these animals had disrupted fractal activity patterns as characterized by more random activity fluctuations at multiple timescales from 4 to 12 h. Intriguingly, these activity disturbances exacerbated when the shift work schedule lasted longer and persisted even in the normal days (without forced activity) following the shift work. The disrupted circadian and fractal patterns resemble those of SCN-lesioned animals and of human patients with dementia, suggesting a detrimental impact of shift work on multiscale activity regulation.

The twenty-first century higher education sector has come a long way after undergoing continuous metamorphosis from pedagogy to andragogy. Most of the educational approaches adopted in medical schools are directed towards developing more of competencies and less of capability, which is the ability to use competencies in novel contexts. Competencies alone are not sufficient to thrive in the present day work place as medical profession subsumes complex contexts; it is in this scenario that, medical educators are entrusted with the challenging task of developing "capable learners". In the heutagogical approach, learners are required to decide upon what to learn and how to learn and therefore the control of the learning process is on the learner and the role of the teacher becomes that of a navigator. This paper highlights the current higher educational practices based on heutagogy, considers its application in the context of Problem-based learning and also discusses a few challenges in incorporating this approach in the existing undergraduate medical curriculum. The article proposes the use of social media in order to support learner autonomy, which in turn improves learners' cognitive engagement with content and tasks, thereby assisting the development of attributes associated with capability.

Children in the United States who are English language learners characteristically do not exhibit the same levels of reading achievement as their peers. The article describes the development of English literacy in English language learners and the relationship between a child's second language (L2) and his or her native language (L1) in literacy development. It is organized first to consider the issue of language of instruction and language transfer, specifically the aspects of L1 literacy that appear to transfer to the second language (L2), English. It then discusses general principles for professionals working to optimize English literacy development in different models of literacy instruction for English language learners. We conclude that using the child's L1 provides the children with strong language and literacy skills in both languages.
Working possible selves--currently activated images of an ideal or feared future self--have been argued to guide one's motivation and actions.

This study examined the effects of physical activity on working memory in older adults using both behavioral and neuroelectric measures. Older adults were assigned to either a higher or lower physical activity group, and event-related potentials were recorded during assessments of a modified Sternberg task. The results indicated that older adults in the higher physical activity group exhibited shorter response times, independent of the working memory load. Enhanced P3 and N1 amplitudes and a decreased P3 latency were observed in the higher physical activity group. These findings suggested that physical activity facilitates working memory by allocating more attentional resources and increasing the efficiency of evaluating the stimulus during the retrieval phase as well as engaging more attentional resources for the early discriminative processes during the encoding phase of a working memory task.

Recent studies have demonstrated that factors influencing perception, such as Gestalt grouping cues, can influence the storage of information in visual working memory (VWM). In some cases, stationary cues, such as stimulus similarity, lead to superior VWM performance. However, the neural correlates underlying these benefits to VWM performance remain unclear. One neural index, the contralateral delay activity (CDA), is an event-related potential that shows increased amplitude according to the number of items held in VWM and asymptotes at an individual's VWM capacity limit. Here, we applied the CDA to determine whether previously reported behavioral benefits supplied by similarity, proximity, and uniform connectedness were reflected as a neural savings such that the CDA amplitude was reduced when these cues were present. We implemented VWM change-detection tasks with arrays including similarity and proximity (Experiment 1); uniform connectedness (Experiments 2a and 2b); and similarity/proximity and uniform connectedness (Experiment 3). The results indicated that when there was a behavioral benefit to VWM, this was echoed by a reduction in CDA amplitude, which suggests more efficient processing. However, not all perceptual grouping cues provided a VWM benefit in the same measure (e.g., accuracy) or of the same magnitude. We also found unexpected interactions between cues. We observed a mixed bag of effects, suggesting that these powerful perceptual grouping benefits are not as predictable in VWM. The current findings indicate that when grouping cues produce behavioral benefits, there is a parallel reduction in the neural resources required to maintain grouped items within VWM.

The influence of the physical activity environment in the home and at work on cardiorespiratory fitness (CRF) and objectively-measured physical activity has not been extensively studied. We recruited 147 women with a (mean ± SD) age of 54 ± 7 years and without evidence of chronic disease. The physical activity environment was assessed by self-report (Assessing Levels of PHysical Activity or ALPHA questionnaire), CRF using a submaximal step test, usual physical activity using combined heart rate and accelerometry, as well as by a validated questionnaire (Recent Physical Activity Questionnaire). Summary scores of the home environment and the work environment derived from the ALPHA questionnaire were positively correlated with CRF after adjustment for age (r = 0.18, p = 0.03 and r = 0.28, p < 0.01, respectively). Women owning a bicycle or having a garden (which may prompt physical activity) had higher CRF; those with a bicycle at home also had a higher physical activity energy expenditure. Similarly, women who had access to fitness equipment at work had higher CRF. In conclusion, these results provide new insights into potential environmental influences on physical capacity and physical activity that could inform the design of physical activity promotion strategies.

The current investigation was undertaken to determine the effects of active versus passive recovery on work performance during repeated bouts of supramaximal exercise. Six healthy sedentary subjects and 9 moderately trained healthy hockey players performed serial 30-second Wingate anaerobic power tests (WAnT) on a bicycle ergometer interposed with 4 minutes of active recovery at a work rate corresponding to 28 % of VO(2)max or passive recovery at rest. Peak power, mean power, total work achieved, and fatigue index were calculated for the serial WAnT. Capillary blood lactate was determined at 5-minute intervals after the last WAnT during 30 minutes of active or passive recovery. Mean power was significantly greater during active recovery in sedentary subjects when compared with passive recovery (388 +/- 42 vs. 303 +/- 37 W, p < 0.05), but did not differ according to recovery mode in moderately trained hockey players (589 +/- 22 W active vs. 563 +/- 26 W passive, p = 0.14). Total work achieved significantly increased during active when compared with passive recovery in sedentary subjects (34 890 +/- 3768 vs. 27 260 +/- 3364 J, p < 0.02) and moderately trained hockey players (86 763 +/- 9151 vs. 75 357 +/- 8281 J, p < 0.05). Capillary blood lactate levels did not differ during active when compared with passive recovery in sedentary subjects but were significantly lower during active when compared with passive recovery in moderately trained hockey players. These data demonstrate that active recovery at a work rate corresponding to 28 % of VO(2)max increases total work achieved during repeated WAnT when compared with passive recovery in sedentary subjects and moderately trained hockey players.

Background: Work-related musculoskeletal pain is one of the occupational hazards in dentists. Aims: To find the prevalence and severity of musculoskeletal pain in dentists, to compare musculoskeletal pain among dentists practicing yoga, those practicing physical activities, and those without any physical activity, and also to know the effects of sex, age, and workload on musculoskeletal pain. Materials and Methods: A self-reporting work-related questionnaire and the Nordic questionnaire for analysis of musculoskeletal disorders were given to graduated dentists attending Indian dental conference in Mumbai, to know the musculoskeletal pain experienced in the last 12 months and feedback was obtained from 220 dentists. Results: The prevalence of musculoskeletal pain in dentists was 34.5%. Prevalence of musculoskeletal pain was 10.5%, 21.7%, and 45.6% in dentists with regular yoga practice, other physical activity, and no physical activity, respectively. There was statistically significant difference in the prevalence of musculoskeletal pain among dentists who were practicing yoga when compared with those in no regular activity group. Conclusion: Within the limitations of the study, there was significant role of physical activity on the quality and quantity of work-related musculoskeletal disorders experienced by dentists. Yoga was found to be more effective than other modes of physical activities. More research is needed on musculoskeletal problems in dentists, with an emphasis on larger sample sizes and correlating other factors like age and sex of the dentists, duration of practice, years of practicing yoga, and working hours per week.

Recent studies have demonstrated the working memory impairment in patients with amnestic mild cognitive impairment (aMCI). However, the neurophysiological basis of the working memory deficit in aMCI is poorly understood. The aim of this study was to explore the abnormal activity during encoding and recognition procedures, as well as the reorganization of the background network maintaining the working memory state in aMCI. Using event-related fMRI during a visuospatial working memory task with three recognition difficulty levels, the task-related activations and network efficiency of the background network in 17 aMCI patients and 19 matched controls were investigated. Compared with cognitively healthy controls, patients with aMCI showed significantly decreased activity in the frontal and visual cortices during the encoding phase, while during the recognition phase, decreased activity was detected in the frontal, parietal, and visual regions. In addition, increased local efficiency was also observed in the background network of patients with aMCI. The results suggest patients with aMCI showed impaired encoding and recognition functions during the visuospatial working memory task, and may pay more effort to maintain the cognitive state. This study extends our understanding of the impaired working memory function in aMCI and provides a new perspective to investigate the compensatory mechanism in aMCI.

It is well known that elite athletes have higher performance in perception, planning, and execution in sports activities relative to novices. It remains controversial, however, whether any differences in basic cognitive functions between experts and novices exist. Furthermore, few studies have directly used functional magnetic resonance imaging (fMRI) to investigate neural activation and deactivation differences between experts and novices while performing visuospatial working memory (WM) tasks. Therefore, the purpose of this study was to examine possible differences in neural activation and deactivation associated with working memory components in processing visuospatial information between archery experts and novices. To this end, we employed a judgment of line orientation (JLO) task, which has a strong WM component. With regard to brain activation, archery experts displayed higher activation in cortical areas associated with visuospatial attention and working memory, including the middle frontal cortex, supplemental motor area, and dorsolateral prefrontal cortex than that of the novices during the performance of the JLO task. With regard to brain deactivation, archery experts exhibited stronger task-related deactivation in cortical areas, such as the paracentral cortex/precuneus and the anterior and posterior cingulate cortex related to the default network, than that of the novices. These results suggest that the archery experts have a strategy that demands greater use of neural correlates associated with visuospatial working memory and attention in addition to greater use of DMN in visuospatial working memory task not directly tied to their domain of expertise.

Human working memory capacity develops during childhood and is a strong predictor of future academic performance, in particular, achievements in mathematics and reading. Predicting working memory development is important for the early identification of children at risk for poor cognitive and academic development. Here we show that structural and functional magnetic resonance imaging data explain variance in children's working memory capacity 2 years later, which was unique variance in addition to that predicted using cognitive tests. While current working memory capacity correlated with frontoparietal cortical activity, the future capacity could be inferred from structure and activity in basal ganglia and thalamus. This gives a novel insight into the neural mechanisms of childhood development and supports the idea that neuroimaging can have a unique role in predicting children's cognitive development.

Shift work is associated with adverse health outcomes. The aim of this study was to explore the effects of shift work on circadian activity rhythms (CARs) and objective and subjective sleep quality in nurses. Female day-shift (n = 16), evening-shift (n = 6), and night-shift (n = 13) nurses wore a wrist actigraph to monitor the activity. We used cosinor analysis and time-frequency analysis to study CARs. Night-shift nurses exhibited the lowest values of circadian rhythm amplitude, acrophase, autocorrelation, and mean of the circadian relative power (CRP), whereas evening-shift workers exhibited the greatest standard deviation of the CRP among the three shift groups. That is, night-shift nurses had less robust CARs and evening-shift nurses had greater variations in CARs compared with nurses who worked other shifts. Our results highlight the importance of assessing CARs to prevent the adverse effects of shift work on nurses' health.

Abstract INTRODUCTION: The importance of work or productive activity for the well-being, community integration, and quality of life of people living with disabilities is addressed, with implications for life care planning and case management. BACKGROUND: The role of work or productive activity in our society, and consequences of deprivation if rehabilitation services do not address vocational effects of disabilities, is explored. A continuum of productivity options is introduced; types of vocational rehabilitation assessment processes and interventions are described. PURPOSE: The role of vocational rehabilitation services in life care planning and case management is discussed, focusing on quality of life for people living with disabilities. CONCLUSION: Rehabilitation and health care professionals should understand the importance of work or other productive activity, and support the development of appropriate plans to address those needs among people who have disabilities.

The objectives of this study were: to identify the representations related to working stress factors attributed by nursing professionals and to discuss the influence of those factors on their work activities. The investigation was developed through a descriptive study with a qualitative approach, using the premises of social representations. The performed studies were used as the framework for the analyses. Data collection was performed using individual semi-structured interviews. The content analysis technique was used to understand the images as representations of nursing workers, the meaning of the stressing factors and their influence on occupational activity. The studied population regularly faces the lack of appropriate working conditions, the scarcity of human and material resources and untrained personnel; Nursing workers feel dissatisfied and present mental and physical fatigue, which are situations that may cause stress when performing occupational activities.

Several lines of evidence suggest that the striatum has an important role in spatial working memory. The neural dynamics in the striatum have been described in tasks with short delay periods (1–4 s), but remain largely uncharacterized for tasks with longer delay periods. We collected and analyzed single unit recordings from the dorsomedial striatum of rats performing a spatial working memory task with delays up to 10 s. We found that neurons were activated sequentially, with the sequences spanning the entire delay period. Surprisingly, this sequential activity was dissociated from stimulus encoding activity, which was present in the same neurons, but preferentially appeared towards the onset of the delay period. These observations contrast with descriptions of sequential dynamics during similar tasks in other brains areas, and clarify the contribution of the striatum to spatial working memory.

A work group was convened to identify the core challenges, content gaps, and corresponding possible solutions for improving food- and physical activity-environment instrumentation. Identified challenges included instrument proliferation, the scaling or grain of instruments and appropriate aggregation to the neighborhood or community level, and unknown sensitivity to change of most instruments. Solutions for addressing these challenges included establishing an interactive and real-time instrument repository, developing and enforcing high standards for instrument reporting, increasing community-researcher collaborations, and implementing surveillance of food and physical activity environment. Solid instrumentation will accelerate a better understanding of food- and physical activity-environment effects on eating and physical activity behaviors.

Gaming experience has been suggested to lead to performance enhancements in a wide variety of working memory tasks. Previous studies have, however, mostly focused on adult expert gamers and have not included measurements of both behavioral performance and brain activity. In the current study, 167 adolescents and young adults (aged 13-24 years) with different amounts of gaming experience performed an n-back working memory task with vowels, with the sensory modality of the vowel stream switching between audition and vision at random intervals. We studied the relationship between self-reported daily gaming activity, working memory (n-back) task performance and related brain activity measured using functional magnetic resonance imaging (fMRI). The results revealed that the extent of daily gaming activity was related to enhancements in both performance accuracy and speed during the most demanding (2-back) level of the working memory task. This improved working memory performance was accompanied by enhanced recruitment of a fronto-parietal cortical network, especially the dorsolateral prefrontal cortex. In contrast, during the less demanding (1-back) level of the task, gaming was associated with decreased activity in the same cortical regions. Our results suggest that a greater degree of daily gaming experience is associated with better working memory functioning and task difficulty-dependent modulation in fronto-parietal brain activity already in adolescence and even when non-expert gamers are studied. The direction of causality within this association cannot be inferred with certainty due to the correlational nature of the current study.
We are publishing these final rules to amend our regulations to carry out section 221(m) of the Social Security Act (the Act). Section 221(m) affects our rules for when we will conduct a continuing disability review if you work and receive benefits under title II of the Act based on disability. (We interpret this section to include you if you receive both title II disability benefits and title XVI (Supplemental Security Income (SSI)) payments based on disability.) It also affects our rules on how we evaluate work activity when we decide if you have engaged in substantial gainful activity for purposes of determining whether your disability has ended. In addition, section 221(m) of the Act affects certain other standards we use when we determine whether your disability continues or ends. We are also amending our regulations concerning how we determine whether your disability continues or ends. These revisions will codify our existing operating instructions for how we consider certain work at the last two steps of our continuing disability review process. We are also revising our disability regulations to incorporate some rules which are contained in another part of our regulations and which apply if you are using a ticket under the Ticket to Work and Self-Sufficiency program (the Ticket to Work program). In addition, we are amending our regulations to eliminate the secondary substantial gainful activity amount that we currently use to evaluate work you did as an employee before January 2001.

Introduction Objective data on the association of maximal aerobic capacity (VO2max) with work related physical activity are sparse. Thus, it is not clear whether occupational physical activity (OPA) contributes to an increase of VO2max. This study examined the association of VO2max with work and non-work related physical activity in a Swiss working population. Methods In this cross-sectional study, a total of 337 healthy and full-time employed adults were recruited. Demographic data, height, weight and BMI were recorded in all subjects. Participants were classified into nine occupational categories (ISCO-88) and merged into three groups with low, moderate, and high OPA. Physical activity was objectively measured by the SenseWear Mini Armband on seven consecutive days (23 hours per day). Participants were regarded as sufficiently active when accumulating ≥30 min of moderate-to-vigorous physical activity per day. VO2max was evaluated using the multistage 20-meter shuttle run test. Results Data of 303 participants were considered for analysis (63% male, age 33 yrs, SD 12). Multiple linear regression analysis (adjusted R2 = 0.69) revealed significant positive associations of VO2max with leisure-time physical activity (LTPA) at vigorous intensity (β = 0.212) and sufficient moderate-to-vigorous physical activity (β = 0.100) on workdays. Female gender (β = -0.622), age (β = -0.264), BMI (β = -0.220), the ratio of maximum to resting heart rate (β = 0.192), occupational group (low vs. high OPA, β = -0.141), and smoking (β = -0.133) were also identified as independent predictors of VO2max. Conclusions The present results suggest that VO2max is positively associated with LTPA, but not with OPA on workdays. This finding emphasizes the need for employees to engage in sufficient high-intensity physical activity in recreation for maintaining or improving VO2max with regard to health benefits. PMID:28045939

Despite recent advances in uncovering the neural signature of tactile working memory processing in animals and humans, the representation of internally modified somatosensory working memory content has not been studied so far. Here, recording EEG in human participants (n = 25) performing a modified delayed match-to-sample task allowed us to disambiguate internally driven memory processing from encoding-related delay activity. After presentation of two distinct vibrotactile frequencies to different index fingers, a visual cue indicated which of the two previous stimuli had to be maintained in working memory throughout a retention interval for subsequent frequency discrimination against a probe stimulus. During cued stimulus maintenance, α activity (8-13 Hz) over early somatosensory cortices was lateralized according to the cued tactile stimulus, even though the location of the stimuli was task irrelevant. The task-relevant memory content, in contrast, was found to be represented in right prefrontal cortex. The key finding was that the visually presented instructions triggered systematic modulations of prefrontal β-band activity (20-25 Hz), which selectively reflected the to-be-maintained frequency of the cued tactile vibration. The results expand previous evidence for parametric representations of vibrotactile frequency in the prefrontal cortex and corroborate a central role of dynamic β-band synchronization during active processing of an analog stimulus quantity in human working memory. In particular, our findings suggest that such processing supports not only sustained maintenance but also purposeful modification and updating of the task-relevant working memory contents.
The web has a lot of information available for teachers about seismology both at informal and at a scientific level. The average student, who approaches the study of seismology for the first time, lacks direct involvement in the study and it often happens that the simple informal knowledge does not result in learning and formalization. The teacher who wants to use web resources for the didactics, finds it is difficult to select information and adapt it to the school level, because of the short weekly time reserved for earth science studies. The seismologist, who gives a lecture in the school, has difficulty to understand how much of the knowledge transmitted will pass to the students. A way to solve these problems is to adopt the Community of Learners' method, creating groups of different-aged students directly involved in research activities and in the production of learning material, using websites organized for web research, production and sharing of ideas, as Jigsaw methodology suggests. The poster shown documents the experience I had with a group of students (aged from 14 to 18) in an Italian high school in Somma Vesuviana, near Naples. The method adopted is adaptable to any kind of technical-scientific issue. In this case seismology was the topic of the work group and thanks to the Community of Learners' method, all the students: -Started as apprentices, learning new things, questioning their knowledge, accessing new sources, using different channels and means of communication and debating with the others; -Moved to the role of teachers, sharing their own knowledge with the others, and explaining their own discoveries; -Became scientists specialized in something unknown to the other students, producers of new and original ideas to explain to the others who had different opinions and ideas. Thanks to the Community of Learners, they all became apprentices, teachers and scientists.

Early deafness can reshape deprived auditory regions to enable the processing of signals from the remaining intact sensory modalities. Cross-modal activation has been observed in auditory regions during non-auditory tasks in early deaf subjects. In hearing subjects, visual working memory can evoke activation of the visual cortex, which further contributes to behavioural performance. In early deaf subjects, however, whether and how auditory regions participate in visual working memory remains unclear. We hypothesized that auditory regions may be involved in visual working memory processing and activation of auditory regions may contribute to the superior behavioural performance of early deaf subjects. In this study, 41 early deaf subjects (22 females and 19 males, age range: 20-26 years, age of onset of deafness < 2 years) and 40 age- and gender-matched hearing controls underwent functional magnetic resonance imaging during a visuo-spatial delayed recognition task that consisted of encoding, maintenance and recognition stages. The early deaf subjects exhibited faster reaction times on the spatial working memory task than did the hearing controls. Compared with hearing controls, deaf subjects exhibited increased activation in the superior temporal gyrus bilaterally during the recognition stage. This increased activation amplitude predicted faster and more accurate working memory performance in deaf subjects. Deaf subjects also had increased activation in the superior temporal gyrus bilaterally during the maintenance stage and in the right superior temporal gyrus during the encoding stage. These increased activation amplitude also predicted faster reaction times on the spatial working memory task in deaf subjects. These findings suggest that cross-modal plasticity occurs in auditory association areas in early deaf subjects. These areas are involved in visuo-spatial working memory. Furthermore, amplitudes of cross-modal activation during the maintenance stage were

The mechanism by which distinct subprocesses in the brain are coordinated is a central conundrum of systems neuroscience. The parietal lobe is thought to play a key role in visual feature integration, and oscillatory activity in the gamma frequency range has been associated with perception of coherent objects and other tasks requiring neural coordination. Here, we examined the neural correlates of integrating mental representations in working memory and hypothesized that parietal gamma activity would be related to the success of cognitive coordination. Working memory is a classic example of a cognitive operation that requires the coordinated processing of different types of information and the contribution of multiple cognitive domains. Using magnetoencephalography (MEG), we report parietal activity in the high gamma (80–100 Hz) range during manipulation of visual and spatial information (colors and angles) in working memory. This parietal gamma activity was significantly higher during manipulation of visual-spatial conjunctions compared with single features. Furthermore, gamma activity correlated with successful performance during the conjunction task but not during the component tasks. Cortical gamma activity in parietal cortex may therefore play a role in cognitive coordination. PMID:21940605

Increased impulsivity and risk-taking are common during adolescence and relate importantly to addictive behaviors. However, the extent to which impulsivity and risk-taking relate to brain activations that mediate cognitive processing is not well understood. Here we examined the relationships between impulsivity and risk-taking and the neural correlates of working memory. Neural activity was measured in 18 adolescents (13-18 years) while they engaged in a working memory task that included verbal and visuospatial components that each involved encoding, rehearsal and recognition stages. Risk-taking and impulsivity were assessed using the Balloon Analogue Risk Task (BART) and the adolescent version of the Barratt Impulsiveness Scale-11 (BIS-11A), respectively. We found overlapping as well as distinct regions subserving the different stages of verbal and visuospatial working memory. In terms of risk-taking, we found a positive correlation between BART scores and activity in subcortical regions (e.g., thalamus, dorsal striatum) recruited during verbal rehearsal, and an inverse correlation between BART scores and cortical regions (e.g., parietal and temporal regions) recruited during visuospatial rehearsal. The BIS-11A evidenced that motor impulsivity was associated with activity in regions recruited during all stages of working memory, while attention and non-planning impulsivity was only associated with activity in regions recruited during recognition. In considering working memory, impulsivity and risk-taking together, both impulsivity and risk-taking were associated with activity in regions recruited during rehearsal; however, during verbal rehearsal, differential correlations were found. Specifically, positive correlations were found between: (1) risk-taking and activity in subcortical regions, including the thalamus and dorsal striatum; and, (2) motor impulsivity and activity in the left inferior frontal gyrus, insula, and dorsolateral prefrontal cortex. Therefore

Much progress has been made in the past 5 to 10 years in measuring and understanding the impact of the food and physical activity environments on behavioral outcomes. Nevertheless, this research is in its infancy. A work group was convened to identify current evidence gaps and barriers in food and physical activity environments and policy research measures, and develop recommendations to guide future directions for measurement and methodologic research efforts. A nominal group process was used to determine six priority areas for food and physical activity environments and policy measures to move the field forward by 2015, including: (1) identify relevant factors in the food and physical activity environments to measure, including those most amenable to change; (2) improve understanding of mechanisms for relationships between the environment and physical activity, diet, and obesity; (3) develop simplified measures that are sensitive to change, valid for different population groups and settings, and responsive to changing trends; (4) evaluate natural experiments to improve understanding of food and physical activity environments and their impact on behaviors and weight; (5) establish surveillance systems to predict and track change over time; and (6) develop standards for adopting effective health-promoting changes to the food and physical activity environments. The recommendations emanating from the work group highlight actions required to advance policy-relevant research related to food and physical activity environments.

Attending and responding to sound location generates increased activity in parietal cortex which may index auditory spatial working memory and/or goal-directed action. Here, we used an n-back task (Experiment 1) and an adaptation paradigm (Experiment 2) to distinguish memory-related activity from that associated with goal-directed action. In Experiment 1, participants indicated, in separate blocks of trials, whether the incoming stimulus was presented at the same location as in the previous trial (1-back) or two trials ago (2-back). Prior to a block of trials, participants were told to use their left or right index finger. Accuracy and reaction times were worse for the 2-back than for the 1-back condition. The analysis of functional magnetic resonance imaging data revealed greater sustained task-related activity in the inferior parietal lobule (IPL) and superior frontal sulcus during 2-back than 1-back after accounting for response-related activity elicited by the targets. Target detection and response execution were also associated with enhanced activity in the IPL bilaterally, though the activation was anterior to that associated with sustained task-related activity. In Experiment 2, we used an event-related design in which participants listened (no response required) to trials that comprised four sounds presented either at the same location or at four different locations. We found larger IPL activation for changes in sound location than for sounds presented at the same location. The IPL activation overlapped with that observed during the auditory spatial working memory task. Together, these results provide converging evidence supporting the role of parietal cortex in auditory spatial working memory which can be dissociated from response selection and execution.

Working memory impairments in schizophrenia have been strongly associated with abnormalities in gamma oscillations within the dorsolateral prefrontal cortex (DLFPC). We recently published the first ever study showing that anodal transcranial Direct Current Stimulation (tDCS) to the left DLPFC was able to significantly improve working memory performance in schizophrenia. In the current paper we present a secondary analysis from this study, specifically looking at the effect of tDCS on gamma activity and its relationship to working memory. In a repeated measures design we assessed the impact of anodal tDCS (1mA, 2mA, sham) on gamma activity in the left DLPFC at three time-points post-stimulation (0min, 20min, 40min). EEG data was available for 16 participants in the 2mA condition, 13 in the 1mA condition and 12 in the sham condition. Following 2mA stimulation we found a significant increase in gamma event-related synchronisation in the left DLPFC, this was in the context of a significantly improved working memory performance. There was also a significant decrease in gamma event-related synchronisation, with no changes in working memory, following sham stimulation. The current study provides preliminary evidence that tDCS may enhance working memory in schizophrenia by restoring normal gamma oscillatory function.

In recent decades, there has been a rise in the use o lean production model techniques. Through this approach, companies become more flexible, a fact that increases the interest in studies regarding the introduction of this model in businesses and its impacts on working conditions. Important observations concerning ergonomics, such as the theme of work activity regulation, have been highlighted in such studies. This article aims to discuss strategies and regulations adopted by the workers on assembly lines that are considered flexible. The article presents the results of a study in a company that adopts some lean production techniques. The study was analyzed using the activity analysis as one of the premises of the Ergonomic Work Analysis (EWA). Many aspects of the traditional assembly line remain present in the scenario that was studied, however a new language was employed and aspects in the nature of regulations demonstrate that the relation with lean production techniques influence the operators' operational modes.

In a normal population the distribution of body mass index (BMI) is such that a certain proportion of the population is likely to be at low values without necessarily being malnourished. However, although they may have low BMIs without being malnourished, they could certainly be physiologically and physically disadvantaged. An attempt is made to dissect out the probability of work capacity and physical activity being influenced by changes occurring in the human body with diminishing BMI. The conclusion reached is therefore that before physical activity is affected, the BMI would probably have to be 17 or less, although it is possible that work capacity might be reduced before this level is reached. In any case, work requiring the use of the body mass - such as carrying loads, digging or shovelling earth or coal, pulling or cycling a rickshaw, stone splitting etc.- would impose a greater stress on people of low BMI.

Neurophysiologic theory and some empirical evidence suggest that fatigue caused by physical work may be more effectively recovered during "diverting" periods of cognitive activity than during passive rest; a phenomenon of great interest in working life. We investigated the extent to which development and recovery of fatigue during repeated bouts of an occupationally relevant reaching task was influenced by the difficulty of a cognitive activity between these bouts. Eighteen male volunteers performed three experimental sessions, consisting of six 7-min bouts of reaching alternating with 3 minutes of a memory test differing in difficulty between sessions. Throughout each session, recordings were made of upper trapezius muscle activity using electromyography (EMG), heart rate and heart rate variability (HRV) using electrocardiography, arterial blood pressure, and perceived fatigue (Borg CR10 scale and SOFI). A test battery before, immediately after and 1 hour after the work period included measurements of maximal shoulder elevation strength (MVC), pressure pain threshold (PPT) over the trapezius muscles, and a submaximal isometric contraction. As expected, perceived fatigue and EMG amplitude increased during the physical work bouts. Recovery did occur between the bouts, but fatigue accumulated throughout the work period. Neither EMG changes nor recovery of perceived fatigue during breaks were influenced by cognitive task difficulty, while heart rate and HRV recovered the most during breaks with the most difficult task. Recovery of perceived fatigue after the 1 hour work period was also most pronounced for the most difficult cognitive condition, while MVC and PPT showed ambiguous patterns, and EMG recovered similarly after all three cognitive protocols. Thus, we could confirm that cognitive tasks between bouts of fatiguing physical work can, indeed, accelerate recovery of some factors associated with fatigue, even if benefits may be moderate and some responses may be

The mechanism for the short-term maintenance of information involves persistent neural activity during the retention interval, which forms a bridge between the cued memoranda and its later contingent response. Here, we used event-related functional magnetic resonance imaging to identify cortical areas with activity that persists throughout working memory delays with the goal of testing if such activity represents visuospatial attention or prospective saccade goals. We did so by comparing two spatial working memory tasks. During a memory-guided saccade (MGS) task, a location was maintained during a delay after which a saccade was generated to the remembered location. During a spatial item recognition (SIR) task identical to MGS until after the delay, a button press indicated whether a newly cued location matched the remembered location. Activity in frontal and parietal areas persisted above baseline and was greater in the hemisphere contralateral to the cued visual field. However, delay-period activity did not differ between the tasks. Notably, in the putative frontal eye field (FEF), delay period activity did not differ despite that the precise metrics of the memory-guided saccade were known during the MGS delay and saccades were never made in SIR. Persistent FEF activity may therefore represent a prioritized attentional map of space, rather than the metrics for saccades.

Facial expressions of emotion constitute a critical portion of our non-verbal social interactions. In addition, the identity of the individual displaying this expression is critical to these interactions as they embody the context in which these expressions will be interpreted. To identify any overlapping and/or unique brain circuitry involved in the processing of these two information streams in a laboratory setting, participants performed a working memory (WM) task (i.e., N-back) in which they were instructed to monitor either the expression (EMO) or the identity (ID) of the same set of face stimuli. Consistent with previous work, during both the EMO and ID tasks, we found a significant increase in activity in dorsolateral prefrontal cortex (DLPFC) supporting its generalized role in WM. Further, individuals that showed greater DLPFC activity during both tasks also showed increased amygdala activity during the EMO task and increased lateral fusiform gyrus activity during the ID task. Importantly, the level of activity in these regions significantly correlated with performance on the respective tasks. These findings provide support for two separate neural circuitries, both involving the DLPFC, supporting working memory for these two distinct aspects of face processing/memory. PMID:21349341

Working memory is the ability to maintain representations of task-relevant information for short periods of time to guide subsequent actions or make decisions. Neurons of the prefrontal cortex exhibit persistent firing during the delay period of working memory tasks. Despite extensive studies, the mechanisms underlying this persistent neural activity remain largely obscure. The neurotransmitter systems of dopamine, NMDA, and GABA have been implicated, but further investigations are necessary to establish their precise roles and relationships. Recent research has suggested a new component: brain-derived neurotrophic factor (BDNF) and its high-affinity receptor, TrkB. We review the research on persistent activity and suggest that BDNF/TrkB signaling in a distinct class of interneurons plays an important role in organizing persistent neural activity at the single-neuron and network levels.

California has a recently documented problem of trans-national environmental lead exposures in imported foods from Mexico but there is limited health information available in immigrant communities about this problem. This report highlights collaborative work with English as a Second Language (ESL) learners to critically review research data on lead exposures and reframe prevention messages about lead contamination of imported foods. These messages are now integrated into ESL curricula for dissemination to Spanish-speaking populations that are disproportionately affected by lead poisoning. This 'learners as interpreters' approach is a participatory method that can be applied across a wide range of public health activities. ESL learners emerged as ideal partners in developing curriculum for lead poisoning prevention for several reasons: the parents expressed strong interest in lead poisoning prevention, several have children under age 6 when lead screenings are recommended, and many have emigrated from regions in Mexico where lead hazards were identified.

Female sex workers (FSWs) who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers’ economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers’ relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

High level of occupational physical activity (PA), contrary to leisure time activities, is generally associated with detrimental health outcomes. We hypothesized that this contrast may be associated with a different pattern of exposure variability in PA, e.g., forward bending of the trunk. The study was conducted on 657 blue-collar workers. Two accelerometers were used to identify the body posture and forward bending of the trunk during work and leisure time. The pattern of forward bending was analyzed using exposure variation analysis (EVA). The recordings comprised of 2.6 ± 0.97 working days in average, with 19.9 ± 8.1 h work and 22.9 ± 8.9 h leisure. The standard deviation and entropy of the EVA profile indicated 11% and 6% (for about 80% of subjects) less variable pattern during work compared with the leisure time, respectively. These new findings contribute to the understanding the paradoxical outcomes of PA during work and leisure.

Working memory is an essential component of human cognition. Persistent activity related to working memory has been reported in many brain areas, including the inferior temporal and prefrontal cortex [1-8]. The medial temporal lobe (MTL) contains "concept cells" that respond invariantly to specific individuals or places whether presented as images, text, or speech [9, 10]. It is unknown, however, whether the MTL also participates in working memory processes. We thus sought to determine whether human MTL neurons respond to images held in working memory. We recorded from patients with chronically intractable epilepsy as they performed a task that required them to remember three or four sequentially presented pictures across a brief delay. 48% of visually selective neurons continued to carry image-specific information after image offset, but most ceased to encode previously presented images after a subsequent presentation of a different image. However, 8% of visually selective neurons encoded previously presented images during a final maintenance period, despite presentation of further images in the intervening interval. Population activity of stimulus-selective neurons predicted behavioral outcome in terms of correct and incorrect responses. These findings indicate that the MTL is part of a brain-wide network for working memory.

Objective: To investigate the prevalence and association between functional disability and health conditions in elderly people. Method: A cross-sectional, population-based study with 1,705 elderly residents in urban region of Florianópolis, Brazil, from September 2009 to July 2010. The functional disability was classified according to the difficulty in accomplishing six basic activities of daily living. The crude and adjusted multinomial logistic regression was used to identify the associated factors. Results: The prevalence of mild functional disability was 38.9%, and it was positively associated with being female, older age, reporting four or more chronic diseases, overweight, and negative self-perception of health. High education and income, having paid work, and being physically active in leisure activities reduced the chance of presenting it. The prevalence of moderate/severe disability was 11.7% and positively associated with older age, presence of depressive symptoms, four or more chronic diseases, and negative self-perception of health. High education, paid work, and being physically active in leisure activities also reduced the chance of presenting moderate/severe disability. Conclusion: Being gainfully employed, having a high level of education, and being physically active in their leisure time reduced the chance of presenting disability. The negative self-perception of health was the factor that most increased the chance of presenting functional disability. PMID:28138470

Transplant programs inform potential donors that they should be able to return to normal activities within ~2 weeks and to work by 6 weeks after laparoscopic nephrectomy. We studied actual time. Between 10/2004 and 9/2014, 911 donors having laparoscopic nephrectomy were surveyed 6 months post-donation. Surveys asked questions specific to their recovery experience, including time to return to normal activities and work and a description of their recovery time relative to pre-donation expectations. Of the 911, 646 (71%) responded: mean age at donation was 43.5±10.6 years; 65% were female, 95% were white, 51% were biologically related to their recipient, and 83% reported education beyond high school. Of the 646 respondents, a total of 35% returned to normal activities by 2 weeks post-donation; 79% by 4 weeks post-donation; 94% by 5-6 weeks; however, 6% took >6 weeks. Of the 646, 551 (85%) were working for pay; of these, mean time to return to work was 5.3±2.8 weeks; median, 5 weeks. Of the 551, a total of 14% returned to work in 1-2 weeks, 46% by 3-4 weeks, and 76% by 5-6 weeks. Importantly, 24% required >6 weeks before returning to work with the highest rates for donors in manual labor or a skilled trade. Significantly longer return to work was reported by females (vs males; P=.01), those without (vs those with) post-high school education (P=.010, those with longer hospital stay (P=.01), and those with a postoperative complication (P=.02). Of respondents, 37% described their recovery time as longer than expected. During the donor informed consent process, additional emphasis on realistic expectations around recovery to baseline activities and return to work is warranted.

This study examined the impact of changes in physical activity, self-efficacy, and self-regulation across the course of a brief intervention on subsequent levels of stress in working mothers. Participants (N = 141) were randomly assigned to an intervention or control condition (2:1 ratio). The intervention was conducted in Illinois between March 2011 and January 2012 and consisted of two group-mediated workshop sessions with content based on social cognitive theory. Participants completed measures of physical activity, self-efficacy, self-regulation, and perceived stress at baseline, immediately postintervention, and 6-month follow-up. Stress levels declined across the 6-month period in both groups. Changes in stress were negatively associated with changes in self-efficacy and self-regulation among intervention participants only. Regression analyses revealed the intervention elicited short-term increases in physical activity, self-efficacy, and self-regulation, but only changes in self-efficacy predicted perceived stress at 6-month follow-up. These results suggest that enhancing self-efficacy is likely to improve working mothers' perceived capabilities to cope with stressors in their lives. Future interventions should continue to focus on increasing self-efficacy to promote improvements in physical activity and psychological well-being in this population.

Dyssynchronous activation of the heart leads to abnormal regional systolic stretch. In vivo studies have suggested that the timing of systolic stretch can affect regional tension and external work development. In the present study, we measured the direct effects of systolic stretch timing on the magnitude of tension and external work development in isolated murine right ventricular papillary muscles. A servomotor was used to impose precisely timed stretches relative to electrical activation while a force transducer measured force output and strain was monitored using a charge-couple device camera and topical markers. Stretches taking place during peak intracellular Ca2+ statistically increased peak tension up to 270%, whereas external work due to stretches in this interval reached values of 500 J/m. An experimental analysis showed that time-varying elastance overestimated peak tension by 100% for stretches occurring after peak isometric tension. The addition of the force-velocity relation explained some effects of stretches occurring before the peak of the Ca2+ transient but had no effect in later stretches. An estimate of transient deactivation was measured by performing quick stretches to dissociate cross-bridges. The timing of transient deactivation explained the remaining differences between the model and experiment. These results suggest that stretch near the start of cardiac tension development substantially increases twitch tension and mechanical work production, whereas late stretches decrease external work. While the increased work can mostly be explained by the time-varying elastance of cardiac muscle, the decreased work in muscles stretched after the peak of the Ca2+ transient is largely due to myofilament deactivation.

While MOOCs offer educational data on a new scale, many educators find great potential of the big data including detailed activity records of every learner. A learner's behavior such as if a learner will drop out from the course can be predicted. How to provide an effective, economical, and scalable method to detect cheating on tests such as surrogate exam-taker is a challenging problem. In this paper, we present a grade predicting method that uses student activity features to predict whether a learner may get a certification if he/she takes a test. The method consists of two-step classifications: motivation classification (MC) and grade classification (GC). The MC divides all learners into three groups including certification earning, video watching, and course sampling. The GC then predicts a certification earning learner may or may not obtain a certification. Our experiment shows that the proposed method can fit the classification model at a fine scale and it is possible to find a surrogate exam-taker. PMID:26884747

Summary Establishing what information is actively maintained in working memory (WM) and how it is represented and controlled is essential to understanding how such information guides future behavior. WM has traditionally been investigated in terms of the maintenance of stimulus-specific information, such as locations or words. More recently, investigators have emphasized the importance of rules that establish relationships between those stimuli and the pending response. The current study used a mental arithmetic task with fMRI to test whether updating of numbers (i.e. stimuli) and updating of mathematical operations (i.e. rules) in WM relies on the same neural system. Results indicate that while a common network is activated by both types of updating, rule updating preferentially activates prefrontal cortex while number updating preferentially activates parietal cortex. The results suggest that both numbers and rules are maintained in WM, but they are different types of information that are controlled independently. PMID:18614038

Objective To identify factors that facilitate adherence to physical activity among employed women. Methods Participants were 103 employed women (Mean 44.4 years ±11.8). Measures included physical activity by accelerometry, location by global positioning systems, and psychosocial constructs, perception of worksite policies and the built environment by questionnaire. Results Meeting physical activity recommendations was significantly associated with use of the built environment, self-regulation, perception of higher land-use mix diversity, and perception of lower infrastructure and safety for walking. Perception of worksite policies, self-efficacy, and social support were not associated with meeting recommendations. Conclusions The findings provide evidence that working women’s physical activity behavior is influenced by both psychosocial and environmental factors. PMID:24765681

The present study used fMRI/BOLD neuroimaging to investigate how visual-verbal working memory is updated when exposed to three different background-noise conditions: speech noise, aircraft noise and silence. The number-updating task that was used can distinguish between "substitution processes," which involve adding new items to the working memory representation and suppressing old items, and "exclusion processes," which involve rejecting new items and maintaining an intact memory set. The current findings supported the findings of a previous study by showing that substitution activated the dorsolateral prefrontal cortex, the posterior medial frontal cortex and the parietal lobes, whereas exclusion activated the anterior medial frontal cortex. Moreover, the prefrontal cortex was activated more by substitution processes when exposed to background speech than when exposed to aircraft noise. These results indicate that (a) the prefrontal cortex plays a special role when task-irrelevant materials should be denied access to working memory and (b) that, when compensating for different types of noise, either different cognitive mechanisms are involved or those cognitive mechanisms that are involved are involved to different degrees.

Overhead work is a known catalyst for occupational shoulder injury. Industrial workers must often adopt awkward overhead postures and loading profiles to complete required tasks, potentially elevating injury risk. This research examined the combined influence of multiple overhead working parameters on upper extremity muscular demands for an industrial drilling application. Twenty-two right-handed males completed 24 unilateral and bilateral overhead work exertions stratified by direction (upward, forward), point of force application (15, 30 and 45 cm in front of the body), and whole-body posture (seated, standing). The dependency of electromyographic (EMG) activity on several factors was established. Significant two-way interactions existed between point of force application and direction (p < 0.0001) and direction and whole body posture (p < 0.0001). An average increase in muscular activity of 6.5% maximal voluntary contraction (MVC) occurred for the contralateral limb when the bilateral task was completed, compared to unilateral tasks, with less than a 1% MVC increase for the active limb. These findings assist evidence-based approaches to overhead tasks, specifically in the construction industry. A bilateral task configuration is recommended to reduce glenohumeral stability demands. As well, particularly for tasks with a far reach distance, design tasks to promote a forward directed exertion. The considerable inter-subject variability suggests that fixed heights are not ideal, and should be avoided, and where this is not possible reaches should be reduced.

Med.,29, 317-320. δ-Aminolevulinic acid dehydrase activity in the blood of men working with lead alkyls. The activity of erythrocyte ALA1-dehydrase is inhibited in vivo at blood lead (Pb2+) levels within the upper range of normal (20-40 μg/100 ml) and in vitro at lead concentrations greater than 10-7 M. In view of the high sensitivity of the enzyme to Pb2+, the levels of enzyme activity in the blood of men occupationally exposed to lead alkyls, particularly tetraethyllead, were measured. It was found that the enzyme activity in an exposed group of men was significantly less (P<0·001) than in a control group, the respective mean values being 220 and 677 units of enzyme activity. Tetraethyllead is metabolized in the body via triethyllead and diethyllead ions. As the latter compound possesses properties similar to Pb2+, it was synthesized in the laboratory and its effect on ALA-dehydrase was studied. Diethyllead ion was found to inhibit ALA-dehydrase activity at concentrations greater than 5 x 10-5 M, although the degree of inhibition was less than that obtained with Pb2+. These results suggest that exposure to tetraethyllead can cause a decrease in erythrocyte ALA-dehydrase activity. PMID:5044603

The aim of the present study was to assess the activity levels of the sternocleidomastoid muscle and upper trapezius muscle during static postures under controlled and standardized conditions, and to determine whether the muscle activity differed between sexes. Electromyographic (EMG) activity was recorded unilaterally from the sternocleidomastoid and upper trapezius muscle in 17 participants whilst they were performing various postural tasks. EMG amplitude was measured by the root mean square values of the raw signals and normalized to peak maximum contractile values for each muscle (%MVC). The intensity of muscle activity was ranked as light (<3%MVC), moderate (3%MVC ≤ EMG ≤ 8%MVC), and substantial (>8%MVC). During most tasks the two muscles contracted light to moderately. Head leaning and shoulder shrugging postures yielded substantial muscle activity in both muscles. Muscle activity did not differ significantly between male and female participants (F = 3.1; p = 0.078). Our findings provided normative values, which will enhance future studies of muscle activity during work in a natural, unrestrained environment.

The purpose of the Extravehicular Mobility Unit (EMU) Work Envelope study is to determine and revise the work envelope defined in NSTS 07700 "System Description and Design Data - Extravehicular Activities" , arising from an action item as a result of the Shoulder Injury Tiger Team findings. The aim of this study is to determine a common work envelope that will encompass a majority of the crew population while minimizing the possibility of shoulder and upper arm injuries. There will be approximately two phases of testing: arm sweep analysis to be performed in the Anthropometry and Biomechanics Facility (ABF), and torso lean testing to be performed on the Precision Air Bearing Facility (PABF). NSTS 07700 defines the preferred work envelope arm reach in terms of maximum reach, and defines the preferred work envelope torso flexibility of a crewmember to be a net 45 degree backwards lean . This test served two functions: to investigate the validity of the standard discussed in NSTS 07700, and to provide recommendations to update this standard if necessary.

OBJECTIVES: To find associations between the prevalence of low back pain and occupational activities. METHODS: Interviews of a random sample of 5185 19-59 year old Danish employees analysed by logistic regression. RESULTS: Increased risks of low back pain were found for "vibration affecting the whole body" (odds ratio (OR) = 1.28), "physically hard work" (OR = 1.28), "frequently twisting or bending" (OR = 1.71), "standing up" (OR = 1.20), and "concentration demands" (OR = 1.28). In the analysis of dose-response relations between low back pain and the risk factors, the one year period prevalence increased with increasing exposure time during a working day to each of the risk factors. The prevalence proportion ratio for those reporting to be exposed for most of the working time were 1.30 for vibrations affecting the whole body, 1.54 for physically hard work, 1.48 for frequently twisting or bending, 1.29 for standing up, and 1.13 for concentration demands. These associations seemed to be stronger in the subset of subjects who worked for 37 hours or more per week. The population attributable fractions were 15.1% for frequently twisting or bending, 15.0% for standing up, 7.6% for concentration demands, and 4.4% for physically hard work. CONCLUSION: Vibrations affecting the whole body, physically hard work, frequently twisting or bending, standing up, and concentration demands proved to be risk factors for the occurrence of low back pain, even after controlling for age, sex, educational level, and duration of employment in a specific occupation.

With growing concerns over the obesity epidemic in the United States and other developed countries, many organizations have taken steps to incorporate healthy workplace practices. However, most workers are still sedentary throughout the day--a major contributor to individual weight gain. The current study sought to gather preliminary evidence of the efficacy of active workstations, which are a possible intervention that could increase employees' physical activity while they are working. We conducted an experimental study, in which boredom, task satisfaction, stress, arousal, and performance were evaluated and compared across 4 randomly assigned conditions: seated workstation, standing workstation, cycling workstation, and walking workstation. Additionally, body mass index (BMI) and exercise habits were examined as moderators to determine whether differences in these variables would relate to increased benefits in active conditions. The results (n = 180) showed general support for the benefits of walking workstations, whereby participants in the walking condition had higher satisfaction and arousal and experienced less boredom and stress than those in the passive conditions. Cycling workstations, on the other hand, tended to relate to reduced satisfaction and performance when compared with other conditions. The moderators did not impact these relationships, indicating that walking workstations might have psychological benefits to individuals, regardless of BMI and exercise habits. The results of this study are a preliminary step in understanding the work implications of active workstations.
Background Promoting walking or cycling to work (active commuting) could help to increase population physical activity levels. According to the habit discontinuity and residential self-selection hypotheses, moving home or workplace is a period when people (re)assess, and may be more likely to change, their travel behavior. Research in this area is dominated by the use of quantitative research methods, but qualitative approaches can provide in-depth insight into the experiences and processes of travel behavior change. This qualitative study aimed to explore experiences and motivations regarding travel behavior around the period of relocation, in an effort to understand how active commuting might be promoted more effectively. Methods Participants were recruited from the Commuting and Health in Cambridge study cohort in the UK. Commuters who had moved home, workplace or both between 2009 and 2010 were identified, and a purposive sample was invited to participate in semi-structured interviews regarding their experiences of, and travel behavior before and after, relocating. A grounded theory approach was taken to analysis. Results Twenty-six commuters participated. Participants were motivated by convenience, speed, cost and reliability when selecting modes of travel for commuting. Physical activity was not a primary motivation, but incidental increases in physical activity were described and valued in association with active commuting, the use of public transport and the use of park-and-ride facilities. Conclusions Emphasizing and improving the relative convenience, cost, speed and reliability of active commuting may be a more promising approach to promoting its uptake than emphasizing the health benefits, at least around the time of relocation. Providing good quality public transport and free car parking within walking or cycling distance of major employment sites may encourage the inclusion of active travel in the journey to work, particularly for people who live too

We evaluated frontal brain activation during a working memory task with graded levels of difficulty in a group of 19 healthy subjects, by means of time-resolved fNIRS technique. Brain activation was computed, and was then separated into a "block-related" and a "tonic" components. Load-related increases of blood oxygenation were studied for the four different levels of task difficulty. Generalized Linear Models were applied to the data in order to explore the metabolic processes occurring during the mental effort and, possibly, their involvement in short term memorization. Results attest the presence of a persistent attentional-related metabolic activity, superimposed to a task-related mnemonic contribution. Moreover, a systemic component probably deriving from the extra-cerebral capillary bed was detected.

Aims Disturbed levels of thyroid hormones are associated with neuropsychiatric disorders, including memory impairments. The aim of this study was to evaluate effects of mild induced thyrotoxicosis on working memory and its neural correlates. Methods Twenty-nine healthy, male subjects with normal thyroid state participated in the study. Functional MRI was acquired during a working memory task (n-back task) before and after ingesting 250 μg L-thyroxin per day for a period of eight weeks. In addition, neuropsychological tests were performed. Results In the hyperthyroid condition the subjects showed slower reaction times, but a higher accuracy in the 0-back version of the memory tasks. Fewer differences between euthyroid and hyperthyroid state were seen for the more difficult conditions of the n-back task. FMRI revealed effects of difficulty in the parahippocampal gyrus, supplementary motor area, prefrontal cortex, anterior cingulate cortex, posterior cerebellum, rolandic operculum and insula (p<0.05, FWE corrected). When comparing euthyroid and hyperthyroid condition in relation to task-induced activation, differences of activation were found in the right prefrontal cortex as well as in the right parahippocampal area. In the psychological assessment, the alerting effect in the Attention Network Task (ANT) and four out of five parameters of the auditory verbal learning test (AVLT) showed an increase from euthyroid to hyperthyroid state. Conclusions It can be concluded that even a short-term intake of thyroid hormones leads to an activation of brain areas associated with working memory and to an improvement of accuracy of working memory tasks.

This study examined whether active or passive cooling during intermittent work reduced the heat strain associated with wearing firefighting protective clothing (FPC) and self-contained breathing apparatus (SCBA) in the heat (35 degrees Celsius, 50% relative humidity). Fifteen male Toronto firefighters participated in the heat-stress trials. Subjects walked at 4.5 km.h(-1) with 0% elevation on an intermittent work (50 min) and rest (30 min) schedule. Work continued until rectal temperature (T(re)) reached 39.5 degrees Celsius, or heart rate (HR) reached 95% of maximum or exhaustion. One of three cooling strategies, forearm submersion (FS), mister (M), and passive cooling (PC) were employed during the rest phases. Tolerance time (TT) and total work time (WT) (min) were significantly increased during FS (178.7 +/- 13.0 and 124.7 +/- 7.94, respectively) and M (139.1 +/- 8.28 and 95.1 +/- 4.96, respectively), compared with PC (108.0 +/- 3.59 and 78.0 +/- 3.59). Furthermore, TT and WT were significantly greater in FS compared with M. Rates of T(re) increase, HR and T-(sk) were significantly lower during active compared with passive cooling. In addition, HR and T(re) values in FS were significantly lower compared with M after the first rest phase. During the first rest phase, T(re) dropped significantly during FS (approximately 0.4 degree Celsius) compared with M (approximately 0.08 degree Celsius) while PC increased (approximately 0.2 degree Celsius). By the end of the second rest period T(re) was 0.9 degree Celsius lower in FS compared with M. The current findings suggest that there is a definite advantage when utilizing forearm submersion compared with other methods of active or passive cooling while wearing FPC and SCBA in the heat.

Electrocorticography (ECoG) and functional MRI (BOLD-fMRI) have been used previously to measure brain activity during working memory delay periods. These studies have separately reported oscillation changes in the theta (4-8 Hz) band and BOLD-fMRI increases during delay periods when information is maintained in memory. However, it is not known how intracranial cortical field potential (CFP) changes relate to BOLD-fMRI responses during delay periods. To answer this question, fMRI was obtained from six epilepsy patients during a visual working memory task. Then, following subdural macroelectrode implant, continuous ECoG was used to record CFPs during the same task. Time-frequency analyses showed delay period gamma band oscillation amplitude increases on electrodes located near fMRI activity, while in the theta band changes were higher for electrodes located away from fMRI activation. The amplitude of the ECoG gamma band response was significantly positively correlated with the fMRI response, while a negative correlation was found for the theta band. The findings are consistent with previous reports of local field potential (LFP) coupling in the gamma band with BOLD-fMRI responses during visual stimulation in monkeys, but are novel in that the relationship reported here persists after the disappearance of visual stimuli while information is being maintained in memory. We conclude that there is a relationship between BOLD-fMRI increases and human working memory delay period gamma oscillation increases and theta decreases. The spectral profile change provides a basis for comparison of working memory delay period BOLD-fMRI with field potential recordings in animals and other human intracranial EEG studies.

Although neural activity associated with emotion is becoming better understood, the influence of affective parameters on brain activity reflecting cognitive functioning in humans remains poorly characterized. We examined affective influences on working memory (WM) and tested the hypotheses that (i) dorsolateral prefrontal cortex (DLPFC) activity reflecting WM is influenced by the emotion-evoking qualities of task-relevant stimuli, but only when brought "on-line" by task demands, and (ii) DLPFC and orbitofrontal cortex (OFC) activities are inversely related as a function of emotional valence. Participants performed two tasks while event-related functional MRI measured brain activity; one task required active maintenance of stimulus representations in WM, and the other task required target detection responses with no demand for WM. Stimuli were standardized emotional (pleasant and unpleasant) and neutral pictures. Emotional stimuli differentially influenced DPFC and OFC activity during WM; DLPFC was influenced by emotional valence, enhanced by pleasant and reduced by unpleasant, compared to neutral stimuli, only when task conditions required WM. OFC was valence-sensitive during both tasks, greater to arousing than neutral stimuli when WM demand was low and in inverse relationship to DLPFC with high WM demand. Further, DLPFC and OFC activities are inversely related with respect to emotional valence during the WM task. The results are consistent with the hypothesis that the intrinsic valence of task-relevant stimuli maintained in WM modulates DLPFC activity but only when the DLPFC is required for task demands. Findings suggest a conceptualization of DLPFC and its involvement in WM that takes into account a role for affective parameters.

Verbal working memory (VWM) engages frontal and temporal/parietal circuits subserving the phonological loop, as well as, superior and inferior cerebellar regions which have projections from these neocortical areas. Different cerebro-cerebellar circuits may be engaged for integrating aurally- and visually-presented information for VWM. The present fMRI study investigated load (2, 4, or 6 letters) and modality (auditory and visual) dependent cerebro-cerebellar VWM activation using a Sternberg task. FMRI revealed modality-independent activations in left frontal (BA 6/9/44), insular, cingulate (BA 32), and bilateral inferior parietal/supramarginal (BA 40) regions, as well as in bilateral superior (HVI) and right inferior (HVIII) cerebellar regions. Visual presentation evoked prominent activations in right superior (HVI/CrusI) cerebellum, bilateral occipital (BA19) and left parietal (BA7/40) cortex while auditory presentation showed robust activations predominantly in bilateral temporal regions (BA21/22). In the cerebellum, we noted a visual to auditory emphasis of function progressing from superior to inferior and from lateral to medial regions. These results extend our previous findings of fMRI activation in cerebro-cerebellar networks during VWM, and demonstrate both modality dependent commonalities and differences in activations with increasing memory load.

How is working memory for different visual categories supported in the brain? Do the same principles of cortical specialization that govern the initial processing and encoding of visual stimuli also apply to their short-term maintenance? We investigated these questions with a delayed discrimination paradigm for faces, bodies, flowers, and scenes and applied both univariate and multivariate analyses to functional magnetic resonance imaging (fMRI) data. Activity during encoding followed the well-known specialization in posterior areas. During the delay interval, activity shifted to frontal and parietal regions but was not specialized for category. Conversely, activity in visual areas returned to baseline during that interval but showed some evidence of category specialization on multivariate pattern analysis (MVPA). We conclude that principles of cortical activation differ between encoding and maintenance of visual material. Whereas perceptual processes rely on specialized regions in occipitotemporal cortex, maintenance involves the activation of a frontoparietal network that seems to require little specialization at the category level. We also confirm previous findings that MVPA can extract information from fMRI signals in the absence of suprathreshold activation and that such signals from visual areas can reflect the material stored in memory.

The high prevalence of low back injuries in nursing has prompted the use of mechanical lift assists while overall assessment of activities and postures remains limited. The purpose of this study was to chronicle trunk posture and work tasks of long-term healthcare professionals. An inclinometer monitored trunk posture for 27 workers, 20 of whom were also observed continuously throughout their shift. Patient lifts and transfers accounted for less than 4% of the shift while patient care, unloaded standing and walking and miscellaneous tasks accounted for 85%. Manual lifts and transfers occurred twice as often as mechanically assisted lifts but took only half the time. The workers had a median trunk flexion angle of 9.2 degrees , spent 25% of their time flexed beyond 30 degrees and had peak flexion angles greater than 75 degrees in many tasks. Analysis of posture throughout the entire working shift indicates that, in addition to lifts and transfers, emphasis needs to be placed on patient care and miscellaneous activities when assessing injury risk for nurses. STATEMENT OF RELEVANCE: Patient handling has been the focus in the effort to reduce back pain and injury in nursing. In addition to the use of mechanical lifts, there is a need to examine other aspects of nursing, including patient care and other ancillary tasks, which comprise the majority of the work shift and, while often unloaded, exhibit extreme postures that may also lead to injury.

Staff development is an important role of the school nurse, yet little is written to assist the nurse in this role. Though some obtain advanced degrees in education, most school nurses are not prepared for the staff development role without further education in pedagogy, teaching strategies, and evaluation methods. This article presents discussion as one of many active teaching strategies that can engage learners and promote critical thinking. More work is needed in the area of course design and implementation, as well as additional research to help identify the most effective teaching strategies for school employees.

Working at a computer is part of a large number of jobs and has been associated with upper extremity musculoskeletal disorders and back pain. The study evaluated the effects of a board attachment on upper extremity and back. The findings are mixed in that the board may have a positive effect in preventing back pain, but may be detrimental to upper extremities. Effect of a desk attachment board on upper extremity and trunk posture, and muscle activity was assessed in women video display terminal users. Participants completed a standard 20-min computer task under two conditions: 1) using a standard desk; 2) using a desk attachment board designed to support the forearms. Bilateral electromyography of the trapezius, multifidus and longissimus muscles and the right anterior deltoid and forearm extensor muscles was recorded. 3-D trunk and upper extremity posture was monitored. Participants were tested before and after 2 weeks of familiarisation with the board in their workplace. Perceived tension and discomfort were recorded before and after use of the board. Use of the board tended to increase muscle activity in the right trapezius and forearm extensor and to decrease muscle activity in the back. Perceived tension in the low back decreased slightly with the board. The board may be useful in reducing tension in the low back during computer work, but may adversely affect the upper extremities.
Over the five year period of performance, thirteen task assignments were issued by the DOE to ARINC Research. During the two year base period seven tasks were assigned. Two task assignments were issued for each of the three consecutive one year option periods. Associated with all task assignments were multiple subtasks, some of which required significant effort. These subtasks are appropriately cited in this report under their respective task assignments as principal work activities or deliverables. The technical and management support provided to the DOE under this contract focused on two general areas: (1) appraisal activities and (2) non-appraisal activities. Support to appraisals included planning, document review, developing lines-of-inquiry, interviewing, data collection, report writing, and follow-up. Such work was executed both on-site at the DOE facility under review and off-site. Non-appraisal support was varied and included such areas as document review, data base development, technical assessments. statistical analysis, policy analysis, reliability engineering, and workshop and conference planning and execution.

This study investigated effects of visual cues, muscular fatigue, task performance and experience of working on inclined surfaces on activity of postural muscles in the lower limbs associated with maintaining balance on three inclined surfaces—0°, 14° and 26°. Normalized electromyographic (NEMG) data were collected on 44 professional roofers bilaterally from the rectus femoris, biceps femoris, tibialii anterior, and gastrocnemii medial muscle groups. The 50th and 95th percentile normalized EMG amplitudes were used as EMG variables. Results showed that inclination angle and task performance caused a significant increase in the NEMG amplitudes of all postural muscles. Visual cues were significantly associated with a decrease in the 95th percentile EMG amplitude for the right gastrocnemius medial and tibialis anterior. Fatigue was related to a significant decrease in the NEMG amplitude for the rectus femoris. Experience of working on inclined surfaces did not have a significant effect on the NEMG amplitude.

Using functional magnetic resonance imaging (fMRI), we investigated prefrontal cortex (PFC) activity during remembering specific source information (format, location judgments) versus remembering that could be based on undifferentiated information, such as familiarity (old/new recognition [ON], recency judgments). A working memory (WM) paradigm with an immediate test yielded greater activation in the lateral PFC for format and location source memory (SM) tasks than ON recognition; this SM-related activity was left lateralized. The same regions of PFC were recruited in Experiment 2 when information was tested immediately and after a filled delay. Substituting recency for location judgments (Experiment 3) resulted in an overall shift in task context that produced greater right PFC activity associated with ON and recency tasks compared to the format task, in addition to left SM-related activity. These data extend to WM previous findings from long-term memory (LTM) indicating that the left and right PFC may be differentially involved in memory attributions depending on the specificity of information evaluated. The findings also provide evidence for the continuity of evaluative processes recruited in WM and LTM.
