Interferometric measurement of glucose by refractive index determination

An apparatus and method for testing the glucose level in a blood sample is provided. The method includes the step of initially filtering a sample of blood to be tested. A beam of light is provided and split into a pair of beams by a beam splitter. The pair of beams travel along generally parallel paths. One path contains a cell of a known optical pathlength and additionally a compensator. The other path has a cell containing the filtered blood sample to be tested. The pair of beams are then recombined by a mirror and a fringe pattern is detected at a detector. From the fringe pattern, the refractive index of the blood sample can be calculated. The refractive index is easily converted to a specific glucose concentration. Alternatively, the original fringe pattern can be restored by changing the effect of the compensator. The refractive index can then be found from the required compensation.https://digitalcommons.mtu.edu/patents/1080/thumbnail.jp

Associations between maternal responsive linguistic input and child language performance at age 4 in a community-based sample of slow-to-talk toddlers

This is the author accepted manuscript. The final version is available from Wiley via the DOI in this recordBACKGROUND: In a community sample of slow-to-talk toddlers, we aimed to (a) quantify how well maternal responsive behaviors at age 2 years predict language ability at age 4 and (b) examine whether maternal responsive behaviors more accurately predict low language status at age 4 than does expressive vocabulary measured at age 2 years. DESIGN OR METHODS: Prospective community-based longitudinal study. At child age 18 months, 1,138 parents completed a 100-word expressive vocabulary checklist within a population survey; 251 (22.1%) children scored ≤20th percentile and were eligible for the current study. Potential predictors at 2 years were (a) responsive language behaviors derived from videotaped parent-child free-play samples and (b) late-talker status. Outcomes were (a) Clinical Evaluation of Language Fundamentals-Preschool Second Edition receptive and expressive language standard score at 4 years and (b) low language status (standard score > 1.25 standard deviations below the mean on expressive or receptive language). RESULTS: Two hundred eight (82.9% of 251) participants were retained to age 4. In adjusted linear regression analyses, maternal expansions predicted higher receptive (p < 0.001, partial R2  = 6.5%) and expressive (p < 0.001, partial R2  = 7.7%), whereas labels predicted lower receptive (p = 0.01, partial R2  = 2.8%) and expressive (p = 0.007, partial R2  = 3.5%) language scores at 4. The logistic regression model containing only responsive behaviors achieved "fair" predictive ability of low language status at age 4 (area under curve [AUC] = 0.79), slightly better than the model containing only late-talker status (AUC = 0.74). This improved to "good" predictive ability with inclusion of other known risk factors (AUC = 0.82). CONCLUSION: A combination of short measures of different dimensions, such as parent responsive behaviors, in addition to a child's earlier language skills increases the ability to predict language outcomes at age 4 to a precision that is approaching clinical value. Research to further enhance predictive values should be a priority, enabling health professionals to identify which slow-to-talk toddlers most likely will or will not experience later poorer language.Let's Learn Language (NHMRC Strategic Award 384491) and Language for Learning (Project Grant 607407) were funded by the Australian National Health and Medical Research Council.

“A very orderly retreat”: Democratic transition in East Germany, 1989-90

East Germany's 1989-90 democratisation is among the best known of East European transitions, but does not lend itself to comparative analysis, due to the singular way in which political reform and democratic consolidation were subsumed by Germany's unification process. Yet aspects of East Germany's democratisation have proved amenable to comparative approaches. This article reviews the comparative literature that refers to East Germany, and finds a schism between those who designate East Germany's transition “regime collapse” and others who contend that it exemplifies “transition through extrication”. It inquires into the merits of each position and finds in favour of the latter. Drawing on primary and secondary literature, as well as archival and interview sources, it portrays a communist elite that was, to a large extent, prepared to adapt to changing circumstances and capable of learning from “reference states” such as Poland. Although East Germany was the Soviet state in which the positions of existing elites were most threatened by democratic transition, here too a surprising number succeeded in maintaining their position while filing across the bridge to market society. A concluding section outlines the alchemy through which their bureaucratic power was transmuted into property and influence in the “new Germany”

Bye-bye mummy: word comprehension in 9-month-old infants

From the little research that exists on the onset of word learning in infants under the age of 1 year, the evidence suggests an idiosyncratic comprehensive vocabulary is developing. To further this field, we tested 49 nine-month-old infants by pre-assessing their vocabularies using a UK version of the MacArthur-Bates Communicative Developmental Inventory. Intermodal preferential looking (IPL) was then used to examine word comprehension including: (a) words parents reported as understood, (b) words infants are expected to understand according to age-related frequency data, and (c) words parents had reported infants not to understand. Assuming parents are good assessors of their infant's early word knowledge, we expected a naming effect with IPL in condition (a), but not condition (c). As language research uses standard samples of words, we expected a discernible naming effect in condition (b). Results show clear IPL evidence of word comprehension for those words that parents reported their infants to understand (condition a). This agreement between methods demonstrates the usefulness of parental communicative developmental inventory in conjunction with IPL to assess infant's individual word knowledge. No naming effects were found for condition (c) and the lack of naming effects in (b) shows that pre-established word lists may not give a sufficiently clear picture of infant's true vocabulary – an important insight for researchers and practitioners alike

The Chalcidoidea bush of life: evolutionary history of a massive radiation of minute wasps.

Chalcidoidea are mostly parasitoid wasps that include as many as 500 000 estimated species. Capturing phylogenetic signal from such a massive radiation can be daunting. Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution. We combined 1007 exons obtained with Anchored Hybrid Enrichment with 1048 ultra-conserved elements (UCEs) for 433 taxa including all extant families, >95% of all subfamilies, and 356 genera chosen to represent the vast diversity of the superfamily. Going back and forth between the molecular results and our collective knowledge of morphology and biology, we detected bias in the analyses that was driven by the saturation of nucleotide data. Our final results are based on a concatenated analysis of the least saturated exons and UCE datasets (2054 loci, 284 106 sites). Our analyses support an expected sister relationship with Mymarommatoidea. Seven previously recognized families were not monophyletic, so support for a new classification is discussed. Natural history in some cases would appear to be more informative than morphology, as illustrated by the elucidation of a clade of plant gall associates and a clade of taxa with planidial first-instar larvae. The phylogeny suggests a transition from smaller soft-bodied wasps to larger and more heavily sclerotized wasps, with egg parasitism as potentially ancestral for the entire superfamily. Deep divergences in Chalcidoidea coincide with an increase in insect families in the fossil record, and an early shift to phytophagy corresponds with the beginning of the "Angiosperm Terrestrial Revolution". Our dating analyses suggest a middle Jurassic origin of 174 Ma (167.3-180.5 Ma) and a crown age of 162.2 Ma (153.9-169.8 Ma) for Chalcidoidea. During the Cretaceous, Chalcidoidea may have undergone a rapid radiation in southern Gondwana with subsequent dispersals to the Northern Hemisphere. This scenario is discussed with regard to knowledge about the host taxa of chalcid wasps, their fossil record and Earth's palaeogeographic history

Análisis sincrónico de la gobernanza universitaria: una mirada teórica a los años sesenta y setenta

Resumen Estudiar las perspectivas en el campo del gobierno de las universidades tiene cada día mayor preeminencia, especialmente si se toma en cuenta la incuestionable necesidad de avanzar hacía organizaciones más eficientes, conectadas con las expectativas que sobre ellas tiene la sociedad. Considerando este escenario, el trabajo se ha planteado como propósito central realizar un análisis de carácter sincrónico del concepto de gobernanza y la constitución de los gobiernos universitarios. Desde el punto de vista metodológico se utilizaron fuentes secundarias: una revisión de papers publicados esencialmente en revistas de habla inglesa. El estudio comprende las décadas del sesenta y el setenta. Se centra en las raíces del concepto de gobernanza universitaria, en la delineación de los actores que participan en sus gobiernos y en las relaciones de poder que fluyen entre ellos.Entre las principales conclusiones, se pueden destacar como el estamento académico desde el principio de las universidades ha ocupado el rol casi plenipotenciario en su respectivo gobierno, producto de esto, en el correr del desarrollo y mientras la complejidad organizacional se incrementaba, es que fue necesario incorporar nuevos actores a los sistemas de gestión; todo lo anterior, teniendo en cuenta que dos elementos han sido fundamentales para la sobrevivencia de este tipo de instituciones, la legitimidad otorgada por la sociedad y los principios de estrategias del ámbito de la gestión
