OBJECTIVE
Among the many milestones of adolescence and young adulthood, transferring from pediatric to adult care is a significant transition for those with type 1 diabetes. The aim of this study was to understand the concerns, expectations, preferences, and experiences of pretransition adolescents and parents and posttransition young adults.

RESEARCH DESIGN AND METHODS
Participants completed questionnaires and responded to open-ended qualitative questions regarding self-management, self-efficacy, and their expectations and experiences with pediatric and adult care providers across the transition process.

RESULTS
At a mean age of 16.1 years, most pretransition adolescents had not yet discussed transferring care with their parents or doctors. Although many posttransition young adults reported positive, supportive interactions, several described challenges locating or establishing a relationship with an adult diabetes care provider. Qualitative themes emerged related to the anticipated timing of transfer, early preparation for transition, the desire for developmentally appropriate interactions with providers, the maintenance of family and social support, and strategies for coordinating care between pediatric and adult care providers.

CONCLUSIONS
Standardizing transition preparation programs in pediatric care and introducing transition-oriented clinics for late adolescents and young adults prior to adult care may help address patients’ preferences and common transfer-related challenges.

OBJECTIVEKnown diabetes is an independent predictor for mortality in coronary artery disease (CAD) patients; however, whether other glucose abnormalities are associated with death risk in CAD patients is unclear. The goal of this study was to examine the association between different glucose states and the risks of all-cause and cardiovascular disease (CVD) mortality among CAD patients.RESEARCH DESIGN AND METHODSThe study cohort included 1,726 CAD patients who were 40–85 years of age in the Guangdong Coronary Artery Disease Cohort. Cox proportional hazards regression models were used to estimate the association of baseline glucose status with risk of mortality.RESULTSDuring a median follow-up of 3.1 years, 129 deaths were recorded, 109 of which were due to CVD. The multivariable-adjusted (age; sex; education; marriage; leisure-time physical activity; smoking; alcohol drinking; BMI; systolic blood pressure; total and HDL cholesterol; glomerular filtration rate; type, severity, duration, and treatment of CAD; history of heart failure; and use of antihypertensive, cholesterol-lowering, and antiplatelet drugs) hazard ratios in normoglycemia, impaired glucose regulation (IGR), newly diagnosed diabetes, and known diabetes were 1.00, 1.58 (95% CI 0.90–2.77), 2.41 (1.42–4.11), and 2.29 (1.36–3.84) for all-cause mortality and 1.00, 1.89 (1.01–3.54), 2.74 (1.50–5.01), and 2.73 (1.52–4.91) for CVD mortality. Assessing fasting plasma glucose only, impaired fasting glucose and newly diagnosed and known diabetes were also associated with increased risks of all-cause and CVD mortality compared with normoglycemia.CONCLUSIONSCAD patients with IGR, newly diagnosed diabetes, and known diabetes have increased risk of CVD mortality.
Higher Magnesium Intake Reduces Risk of Impaired Glucose and Insulin Metabolism and Progression From Prediabetes to Diabetes in Middle-Aged Americans
Authors: Hruby Adela , Meigs James B. , O’Donnell Christopher J. , Jacques Paul F. , McKeown Nicola M. 
Published: October 2013

OBJECTIVE
To assess 7-year associations between magnesium intake and incident prediabetes and/or insulin resistance (IR), and progression from these states to type 2 diabetes.

RESEARCH DESIGN AND METHODS
In 2,582 community-dwelling participants 26–81 years old at baseline, magnesium intake and risk of incident “metabolic impairment,” defined as impaired fasting glucose (FG) (≥5.6 to &lt;7.0 mmol/L), impaired glucose tolerance (2-h postload glucose ≥7.8 to &lt;11.1 mmol/L), IR, or hyperinsulinemia (≥90th percentile of homeostasis model assessment of IR or fasting insulin, respectively), was estimated among those with normal baseline status, and risk of incident diabetes was estimated among those with baseline metabolic impairment. In participants without incident diabetes, we examined magnesium intake in relation to 7-year changes in fasting and postload glucose and insulin, IR, and insulin sensitivity.

RESULTS
After adjusting for age, sex, and energy intake, compared with those with the lowest magnesium intake, those with the highest intake had 37% lower risk of incident metabolic impairment (P trend = 0.02), and in those with baseline metabolic impairment, higher intake was associated with 32% lower risk of incident diabetes (P trend = 0.05). In the combined population, the risk in those with the highest intake was 53% (P trend = 0.0004) of those with the lowest intake. Adjusting for risk factors and dietary fiber attenuated associations in the baseline normal population but did not substantially affect associations in the metabolically impaired. Higher magnesium intake tended to associate with lower follow-up FG and IR, but not fasting insulin, postload values, or insulin sensitivity.

CONCLUSIONS
Magnesium intake may be particularly beneficial in offsetting risk of developing diabetes among those at high risk. Magnesium’s long-term associations with non–steady-state (dynamic) measures deserve further research.
Stability bands for moving solitons in uniform and inhomogeneous damped ac-driven circular Toda lattices
Authors: Vergara Lautaro , Malomed Boris 
Published: October 2013

Abstract
By means of systematic simulations, we study the motion of discrete solitons in weakly dissipative Toda lattices (TLs) with periodic boundary conditions, resonantly driven by a spatially staggered time-periodic (ac) force. A complex set of alternating stability bands and instability gaps, including scattered isolated stability points, is revealed in the parametric plane of the soliton’s velocity and forcing amplitude for a given size of the circular lattice. The analysis is also reported for the circular TL including a single light- or heavymass defect. The stability chart as a whole shrinks and eventually disappears with the increase of the lattice’s size and strength of the mass defect. Qualitative explanations to these findings are proposed. We also report the dependence of the stability area on the initial position of the soliton, finding that the area is largest for some intersite position. For a pair of solitons traveling in opposite directions, there exist regimes where both solitons survive periodic collisions in small-size lattices.
Regional diversity in the socio-economic situation
of Poland’s rural population in the period 1967-2001, assessed by anthropological methods
Authors: Łaska-Mierzejewska Teresa , Olszewska Elżbieta 
Published: October 2013

Abstract
The analysis covered girls, aged 9-18, from farmer, farmer-worker and non-farmer rural families inhabiting 4 regions of Poland. Additionally, parents’ education, number of children per family and the wealth of the family were recorded. The aim of the study was to assess the impact of social stratification of the rural population, the economic crisis (1978-1989) and political and economic transition (1989) on the girls’ biological maturation. Age at menarche and body height were used as biological measures of living conditions. In the period 1967-1977 a marked acceleration in maturation and a significant increase in average body height were noted. The study repeated in 1987 demonstrated negative effects of the economic crisis (1977-1989). Research findings from 2001, after the political system transformation, provide evidence ‘compensating for losses’ recorded in girls’ biological condition during the crisis. The diversity of biogeographic and socioeconomic conditions of rural inhabitants in the studied regions is reflected in a marked diversification in age of menarche and body height.
La forêt des Erses, laboratoire du contrôle et patrimoine exceptionnel

The forest of Les Erses: a monitoring laboratory and an outstanding heritage
The forest of Les Erses is situated at an altitude of 1100 m in the Jura mountains in Switzerland. It contains mixed stands of varying degrees of irregularity, and since 1889 has been the subject of uninterrupted records made by the pioneers of selection silviculture by the check method, Henry Biolley and William Borel, and then by the foresters of the Service of forests, wildlife and nature of the canton of Vaud. Since 1967, monitoring of individual stems of over 10 cm diameter in 59 permanent sample plots has demonstrated a positive trend in total wood production, and in stem diameter. This is probably an effect of global warming and improvement in the soils freed from grazing pressure. The processes of recruitment, growth and removal of the stems are complex: however, the relevance of the models used by the canton of Vaud to manage the forests in a sustainable way has been demonstrated. Although silvicultural objectives vary according to technical progress, the interests of the owners, the needs of society and, today, climate change, monitoring the development of forest stands is the core of a responsible sustainability policy. The concepts and enquiries of Biolley and Borel are still relevant after 120 years of silvicultural history in the forest of les Erses, even though today's concepts of monitoring have gone beyond the narrow frame in which the pioneers developed it.
Genetic diversity in three endangered pitcher plant species (Sarracenia; Sarraceniaceae) is lower than widespread congeners
Authors: Furches M. Steven , Small Randall L. , Furches Anna 
Published: October 2013

•Premise of the study:Narrow‐ranging, rare species often exhibit levels of genetic diversity lower than more common or widespread congeners. These taxa are at increased risk of extinction due to threats associated with natural as well as anthropogenic events. We assessed genetic variation in three federally endangeredSarraceniaspecies. We discuss maintenance of genetic diversity and evolutionary implications of rarity.•Methods:We analyzed three noncoding chloroplast regions and nine microsatellite loci in populations spanning the geographic ranges ofS. oreophila,S. alabamensis, andS. jonesii. The same microsatellite loci were used to examine a single field site of three more widespread species (S. alata,S. leucophylla, andS. rubrasubsp.wherryi).•Key results:All three endangered species have experienced reductions in population size and numbers. All show considerably less variation than more widespread members of the genus.Sarracenia alabamensismaintains the greatest microsatellite variation but has the fewest remaining populations and may be under the greatest threat. More widespreadS. oreophilamaintains surprising chloroplast diversity, yet exhibits little microsatellite diversity.Sarracenia jonesiilacks chloroplast diversity, yet maintains greater microsatellite diversity thanS. oreophila.•Conclusions:The three endangered species differ in levels and structure of diversity, yet not in predictable ways, emphasizing that unique demographic and ecological histories, rather than current distribution and population size, best explain present patterns of genetic variation. Maintenance of remaining genetic variation is important, but preventing further habitat loss and degradation is critical.
Hybridization leads to interspecific gene flow in Sarracenia (Sarraceniaceae)
Authors: Furches M. Steven , Small Randall L. , Furches Anna 
Published: October 2013

• Premise of the study: The role of hybridization in plant evolution remains a source of intense debate. Potential consequences range from genetic dead‐ends to species fusion or hybrid speciation. While much has been learned from model systems such as Populus, Iris, and Helianthus, many questions remain. Consisting of 11 species that are all capable of hybridizing, Sarracenia presents an excellent system in which to study hybridization.• Methods: Using microsatellites, we examined a single field site consisting of three species: S. leucophylla, S. alata, and S. rubra subsp. wherryi. We determined the level of genetic admixture and compared it with allopatric sites of the same taxa.• Key results: In contrast to the well‐defined clusters formed when we examined the allopatric sites, the sympatric field site exhibited a wide range of admixture. Additionally, when the relative genetic makeup of “pure” species at the site was compared with the makeup of hybrids, we found that Sarracenia alata contributed disproportionately to the hybrid genomes.• Conclusions: Our study provides further evidence that hybridization is contributing to interspecific gene flow in the genus and that all species do not contribute equally to hybridization. Implications for conservation are discussed.
Les diamants (de Bokassa) sont éternels
Authors: Bat Jean-Pierre 
Published: October 2013

Bois « sacré » du domaine réservé du chef de l’État sous la V e République, l’Afrique est passée du « secret du roi » incarné par Jacques Foccart aux feux médiatiques des scandales. Ce changement de registre, dont « l’affaire des diamants » constitue l’archétype, a profondément altéré l’interprétation de la politique africaine de la France. Pensée comme le socle du programme d’indépendance nationale imaginée par le général de Gaulle, elle a été réduite à une succession d’affaires, parsemées des ombres inquiétantes de « barbouzes ». L’archéologie du récit (médiatique) de la « Françafrique » doit permettre de comprendre le « syndrome Foccart », par-delà les fantasmes attachés à la cellule africaine de l’Élysée vue comme la plus secrète boîte noire de la République.
Geographic Variation in Liver Metal Concentrations of Greater Sage-Grouse
Authors: Blomberg Erik J. , Wolff Peregrine L. , Sedinger James S. 
Published: October 2013

Abstract
Populations of greater sage-grouse (Centrocercus urophasianus) have declined throughout the species' range. We evaluated metal concentrations in livers sampled from greater sage-grouse collected from hunters in Eureka County, Nevada, during autumn of 2008 and 2010. We make local comparisons of metal concentrations between two populations of greater sage-grouse in Eureka County, as well as regional comparisons with previously reported values for greater sage-grouse collected in Wyoming and Montana. With one exception, tissue concentrations of lead, arsenic, and mercury were below method detection limits. Mean concentrations of iron, molybdenum, and zinc differed between the two Nevada populations, and magnesium, cadmium, molybdenum, and selenium differed between greater sage-grouse in eastern Nevada, and values reported for Wyoming and Montana. In contrast, we found no evidence for local variation in magnesium, copper, cadmium, or selenium, or for regional variation in iron, zinc, or copper. Of particular interest were low selenium concentrations in our study system relative to Wyoming and Montana. Some individuals in our study returned liver selenium values considered consistent with selenium deficiency in domestic poultry. This research adds to the small body of literature on background contaminant levels in greater sage-grouse, and provides evidence for geographic variation in metal concentrations at local and regional scales.
Establishing Electronic Health Record Competency Testing for First-Year Residents
Authors: Nuovo Jim , Hutchinson David , Balsbaugh Thomas , Keenan Craig 
Published: October 2013

Abstract

Background
Despite widespread use of electronic health records (EHRs), it is unclear whether residents possess the EHR skills to perform required tasks.

Objective
We assessed first-year residents' skills on specific EHR tasks.

Methods
Incoming residents were required to participate in EHR training before starting clinical rotations. The training team developed an assessment tool for 19 EHR tasks. Senior residents used a structured template to assess interns.

Results
For ambulatory workflow skills, most participants (range, 70%–100%) demonstrated competence. The 3 skills for which interns needed the most assistance were (1) creating and routing a result note (17 of 68, 25%), (2) deleting a medication or changing a dose in reconciling medications (10 of 68, 15%), and (3) finding results for the past 90 days (10 of 68, 15%). For inpatient workflow skills, most interns (range, 63%–100%) demonstrated competence. The 3 skills in which interns needed the most assistance were (1) placing a referral order at discharge (23 of 68, 34%), (2) finding a temperature on a flow sheet and trending it over time (14 of 68, 21%), and (3) creating a discharge summary, having it reviewed, and forwarding it to the primary care physician (14 of 68, 21%).

Conclusions
Our results should help EHR training teams at other institutions to better understand the strengths and weakness of EHR training approaches and to target training on tasks with the greatest performance deficits as well as toward underperforming individuals or groups.
Creating coherent incidental learning journeys on mobile devices through feedback and progress indicators

Published: October 2013

AbstractTimely and appropriate feedback and indicators of progress can motivate learners. Mobile learning poses a challenge to established instructional strategies with respect to delivering feedback and monitoring learner progress, particularly in informal and incidental learning occurring outside of formal structured learning environments. We argue that well-designed and managed feedback and progress indicators can offer guidance and a sense of structure to learners in the absence of a formal curriculum, accreditation or set outcomes. Furthermore, they can encourage casual users of mobile applications to move from fragmented learning episodes towards a more long term and reflective learning journey. In this paper we describe how we are developing feedback and progress indicators for the EU-funded MASELTOV project, which explores how smartphones can support language learning and social inclusion for recent immigrants to Europe. Presenting educational services and materials on mobile devices allows learning episodes to be incorporated into daily activities and schedules, to be accessed at times and in places that suit learners best. Feedback and progress indicators embedded into these services may motivate such an audience to reconceptualise fragmentary, ephemeral educational experiences into a more coherent, sustained learning journey. We describe how feedback and progress indicators have been used successfully in web-based and games-based learning, and our assessment of which types may best support incidental mobile learning and the challenges we face.
Mobile learning through indigenous languages: learning through a constructivist approach
Authors: Jantjies Mmaki , Joy Mike 
Published: October 2013

AbstractAn increase in accessible electronic pedagogy available in African languages is vital in extending learning resources to resource constrained schools and multilingual communities. The lack of appropriate mobile and electronic resources in these contexts often limits learners from participating in the digital age and discovering knowledge through technology. South Africa, used as the context for this study, has eleven official languages and promotes their use for education in schools. There are however limited bilingual resources that support bilingual education. The different challenges, such as the limited resources that enable an effective learning environment, often make it difficult for teachers to create new learning environments that embrace technology in classrooms.
This paper presents a case study that evaluates the potential use of mobile learning to support the current informal learning process for resource constrained multilingual high school learners. In the study learners created their own audio based bilingual learning material on mobile phones using a constructivist learning approach, in the subject area of physical science. A total of 32 high school learners and their teacher from a South African school participated in the study, and though semi–structured interviews and questionnaires learners reported on their experiences. Infrastructure challenges, including limited access to free electronic resources, and slow and expensive Internet access, became the main hurdles in supporting a constructivist learning environment. The mobile learning process however gave learners an opportunity to create their learning content in their own languages at any location at any time, and use the content later for revision.
Academic Achievement in BYOD Classrooms

Published: October 2013

AbstractA product of the new STEM democracy is the development of indigenous high-technology capabilities.We maintain when effective mobile learning is incorporated into a receptive learning environment studentachievement will increase. Also, the ubiquitousness of mobile devices prepares students for the STEM focusedglobalized economy because the devices are consistently used for the communication and informational needs ofstudents and teachers inside and outside of learning environments. Mobile learning devices (MLDs) are relativelyaffordable and accessible, and often reinforce difficult learning concepts and a mechanism for collaboration outsideregular school hours. Mobile learning technology levels the learning field, due to the relatively low cost,accessibility in most households, including those that lack laptop or desktop computers and connection to theinternet. Under Bring Your Own Device (BYOD) policy, this study centers on assessing the effectiveness of MLDson the academic achievement of students in 8th and 10th grades. We were interested to understand the effectivenessof BYOD integration in the classroom based on student achievement and student response to determine the extent ofvariance, if any, between those classrooms that use BYOD technology extensively in comparison to those that donot. The study uses previously collected school system data (removing all individual identifiers by the schoolsystem’s curriculum coordinator). This research is significant, since there is a paucity of large scale research toassess the level of student achievement, as expressed through standardized assessments, related to the BYOD policy.
