In a meta-analysis of articles employing clustering methods, we find that little attention is paid to remaining within-cluster heterogeneity and that average values are relatively high. We suggest addressing this potentially problematic "dark side" of cluster analysis by providing two coefficients as standard information in any cluster analysis findings: a goodness-of-fit measure and a measure which relates explained variation of analysed empirical data to explained variation of simulated random data. The second coefficient is referred to as the Index of Clustering Appropriateness (ICA). Finally, we develop a classification scheme depicting acceptable levels of remaining within-cluster heterogeneity. (authors' abstract)

The Sibling Niche Differentiation Model (Sulloway, 1996) suggests that an individual’s birth order acting as a proxy for within-family environmental factors like age, size and strength relative to ones siblings influences the strategies used to gain resources and minimize sibling conflict. Recent within-family birth order research (for example Paulhus, Trapnell and Chen, 1999; Healey & Ellis, 2007) has found a systematic effect of birth order on personality, with firstborn siblings found to be more conscientious and secondborn siblings more open to experience. However, an examination of birth-order effects by independent raters, has been lacking in the birth order literature. Furthermore no prior examination comparing the type of stimulus material used to elicit participant responses has been conducted. Study 1 (N = 203) sought to replicate previous birth order findings for the two Big-5 traits Conscientiousness and Openness to Experience, while also testing an alternative explanation (hypo-masculinization hypothesis) for observed birth-order differences (Beer & Horn, 2000). Study 2 compared the efficacy of four different types of stimulus material (rankings, ratings, independent ratings and real-world scenarios) in observing birth order effects (combined N = 544), while also testing novel predictions about the saliency and generalisability of birth-order effects on personality outside the context of the family. General support was found for the Sibling Niche Differentiation Model across studies and across stimulus materials, but limited support was found for the nature of within family personality differences between siblings extending to contexts outside the family environment.

Objective: This dissertation was undertaken to explore the clinical utility of physiological and behavioural metrics of neurocognitive adaptability in the screening of older adults for possible early signs of pathological cognitive aging. Methods: This was an intensive, multi-method study of 44 healthy (non-demented) Victoria-area older adults (ages 65 to 80 years). Study 1 examined timescale-specific differences in resting electroencephalographic (EEG) adaptability as a function of subtle cognitive decline. Study 2 described differences in retest practice effect -- within and across a burst of 4 to 6 occasions of computerized cognitive testing -- with respect to individual variation in estimated premorbid function and self-reported conscientiousness. Study 3 considered whether practice effects from Study 2 were related to individual differences in the resting EEG marker derived in Study 1, above and beyond the differences due to premorbid function and conscientiousness. Results: Study 1 revealed that older adults with neuropsychological performance indicators of subtle cognitive decline also showed subtle, timescale-specific differences in resting EEG adaptability. Study 2 illustrated the differentiable effects of individual differences in estimated premorbid function and conscientiousness on within- and across-occasion improvement on a computerized attention-shifting (switch) task. Study 3 demonstrated the unique promotional effects exerted by conscientiousness and resting EEG adaptability on the rate of across-occasion improvement in cognitive performance. Conclusions: Useful yet under-used tools for detecting early signs of neurocognitive decline include rigorous, standardized neuropsychological diagnostic criteria, the magnitude of practice-related improvement in cognitive performance, and characteristics of the brain's resting electrical activity. Future multi-method, ecologically-situated studies are needed to establish standardized protocol that can be used to screen growing worldwide numbers of older adults for losses in neurocognitive adaptability that may herald the earliest stages of pathological neurocognitive aging. / Graduate

Chinese contemporary art start in 1979, the new art era has led to the emergence of a large number of art workers (artists). Workshop with large space and quiet environment would be the ideal place to do the artwork, Huantie Art District is one of the ideal places in China (Beijing), with low rent and big empty space. In 2017, Huantie Art District faces demolition and reconstruction because of the informal construction, security problem ( the structure of the building), and land-use problems. This kind of situation also occurred in other art districts. From this, I began to think about what kind of way can we help artists maintain their creation and survival in Beijing, as an architecture student, what can I do for them. To weave the broken land, protect the Art District, have a sense of belonging, and become a city within city.

Humans tend to view those with similar characteristics to their own more favorably than those with dissimilar characteristics. Mahajan and Wynn (2012) suggest this phenomenon is rooted in an innate preference for similarity to self and is enhanced by the salience of the similar characteristic(s). This conclusion was based on results from a study conducted by Mahajan and Wynn showing that infants who chose a food prior to choosing a puppet (High Salience condition) preferred the puppet with the same food preference, whereas infants who chose a food after choosing a puppet (Low Salience condition) showed no preference based on a single measure of choice. However, their results may have been affected by factors other than infant preference such as parental bias or side bias. The purpose of the present study was to replicate Mahajan and Wynn's (2012) Low Salience condition and extend it by assigning 20 infants and their parents (10 infants/parent dyads per group) to either (a) a between group manipulation in which infants' food preference was made "salient" to parents (but not infants) in only one group, or (b) a within-subject repeated measures of infants' choices. Results suggested that the manipulation may have been insufficient to assess parental bias; however, more infants (75%) chose a puppet presented on one side more often than a particular puppet (e.g., similar or dissimilar) suggesting infants' choices may be more a product of side bias than puppet preference.
