Longitudinal profiling of mild congitive impairment subtypes
No full textRecently it was suggested that longitudinal cognitive assessments, although not essential for an MCI classification, are preferable to tracking the trajectory of MCI individuals (Albert et al., 2011). This aligns with previous findings that report instability among MCI cohorts, particularly in cross-sectional studies (Saunders and Summers, 2011; de Jager and Budge, 2005). The sensitivity and specificity of MCI classification is known to be enhanced by assessing multiple cognitive domains. The aim of the present study was to examine the neuropsychological profile of MCI subtypes 12 months after a classification assessment
Wealthier is healthier
No full textWith cross-country, time series data on health (infant and child mortality, and life expectancy) and per capita income, the authors estimate the effect of income on health. They use instrumental variables estimation to identify the effect of income on health that is structural and causal, isolated from reverse causation (healthier workers are more productive and hence wealthier) or incidental association (some other factor may cause both better health and greater wealth). The long-run income elasticity of infant and child mortality in developing countries lies between 0.2 and 0.4. Using those estimates, they calculate that in 1990 alone, more than half a million child deaths in the developing world could be attributed to poor economic performance in the 1980s.Health Economics&Finance,Inequality,Economic Theory&Research,Governance Indicators,Health Monitoring&Evaluation
Microspore developmental stage and anther length influence the induction of tomato anther callus
No full textAnthers of L680A, Licato and Ailsa Craig tomato (Lycopersicon esculentum) were plated on Doy's basal medium 1 to determine whether microspore developmental stage and anther length influence anther callus production. Although calli were induced at all stages of anther development, anthers containing prophase I-stage microspores produced the highest frequency of calli. Fewer calli were produced as microspores approached the uninucleate and binucleate pollen stage. Callus diameter also decreased as anther development progressed. Significantly larger calli were produced from prophase I than later-stage anthers. Time of anther harvest (morning vs. afternoon) did not significantly affect callus number or diameter. Anther and flower bud length were both significantly correlated with anther developmental stage, the number of anthers producing calli, and mean calli diameter. In each case, anther length exhibited a significantly better correlation than bud length..RE: 20 ref.; SC: CA; HO; PL; 0C; 0P; 7BSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0018-5345&isbn=&volume=27&issue=7&spage=838&pages=838-840&date=1992&title=HortScience%20&atitle=Microspore%20developmental%20stage%20and%20anther%20length%20influence%20the%20induction%20of%20tomato%20anther%20callus.&aulast=Summers&pid=%3Cauthor%3ESummers%2c%20W%20L%3bJaramillo%2c%20J%3bBailey%2c%20T%3C%2Fauthor%3E%3CAN%3E19931642181%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
The end of adolescence in "Four Summers" in Oates's The Wheel of Love
No full textP(論文)This interpretative study of J. C. Oates' s "Four Summers" concludes my analysis of all twenty stories in The Wheel of Love. This is the seventh and last study. All the stories were discussed in my previous studies appeared in this bulletin. Oates depicts another story about a young girl, her coming of age and the difficulties when she determines the choice of her partner. The life of Sissie, the main character, is view from the eyes of the author. As in previous parts, we see a character who is vacillating between hope and fear."departmental bulletin pape

Diagnostic accuracy of memory measures in alzheimer’s dementia and mild cognitive impairment: A systematic review and meta-analysis
No full textDepression Anxiety Stress Scales-21: Factor Structure and Test-Retest Invariance, and Temporal Stability and Uniqueness of Latent Factors in Older Adults
No full textThis study examined the factor structure and test-retest invariance, and temporal stability and uniqueness of the latent factors (depression, anxiety, and stress) of the Depression Anxiety Stress Scales-21 (DASS-21; Lovibond & Lovibond, 1995) in group a of 269 older adults (age ranging from 60 to 85 years) from the general community. Participants completed the DASS-21 twice, 3 months apart. Confirmatory factor analysis (CFA) of their ratings at Time 1 indicated support for the original 3-factor oblique model (factors for depression, anxiety, and stress). Additional analyses showed support for test-retest invariance for both the measurement (configural, metric and thresholds) and structural (variances and covariances) components of this model. Results also indicated temporal stability and uniqueness of the latent factors. The practical, theoretical, research and clinical implications of the findings are discussed
A first survey of the global population size and distribution of the Scottish Crossbill Loxia scotica
No full text"The survey was part-financed by Scottish Natural Heritage"A survey of Scottish Crossbills Loxia scotica was carried out in 3,506 km2 of conifer woodland in northern Scotland during January to April 2008 to provide the first estimate of the global population size for this endemic bird. Population estimates were also made for Common Crossbills L. curvirostra and Parrot Crossbills L. pytyopsittacus within this range. Crossbills were lured to systematically selected survey points for counting, sexing and recording their calls for later call-type (species) identification from sonograms. Crossbills were located at 451 of the 852 survey points, and adequate tape-recordings made at 387 of these. The Scottish Crossbill had a disjunct distribution, occurring largely within the eastern part of the study area, but also in the northwest. Common Crossbills had a mainly westerly distribution. The population size of postjuvenile Scottish Crossbills was estimated as 13,600 (95%C.I. 8,130–22,700), which will approximate to 6,800 (4,065–11,350) pairs. Common Crossbills were more abundant within this range (27,100, 95% C.I. 14,700–38,400) and Parrot Crossbills rare (about 100). The sex ratio was not significantly different from parity for Scottish Crossbills. The modal number at survey points was two but numbers were larger in January than later in the survey. The numbers and distribution of all crossbill species are likely to vary between years, depending upon the size of the cone crops of the different conifers: all were coning in 2008. Common Crossbill and Parrot Crossbill numbers will also be affected by irruptions from continental Europe. A monitoring scheme is required to detect any population trend, and further work on their habitat requirement (e.g. conifer selection at different seasons) is needed to inform habitat management of native and planted conifer forests to ensure a secure future for this endemic bird.Peer reviewe
Distinguishing the cognitive processes of mindfulness: Developing a standardised mindfulness technique for use in longitudinal randomised control trials
No full textA capacity model of mindfulness is adopted to differentiate the cognitive faculty of mindfulness from the metacognitive processes required to cultivate this faculty in mindfulness training. The model provides an explanatory framework incorporating both the developmental progression from focussed attention to open monitoring styles of mindfulness practice, along with the development of equanimity and insight. A standardised technique for activating these processes without the addition of secondary components is then introduced. Mindfulness-based interventions currently available for use in randomised control trials introduce components ancillary to the cognitive processes of mindfulness, limiting their ability to draw clear causative inferences. The standardised technique presented here does not introduce such ancillary factors, rendering it a valuable tool with which to investigate the processes activated in mindfulness practice
