    The root causes of Stope Slippage at Kidd Mine, Canada

    No full text
    Kidd Mine has a production target of 2.5 million tonnes of ore per year in 2010. Seventy-five stopes are turned over to the next stope in order to achieve this annual production. Each turnover from stope to stope has an anticipated number of days based on the geomechanical relation between them. Due to the depth and size of the operation, it is crucial that this turnover takes place within the anticipated time to avoid delays in the mining sequence and cycle and set-backs in production. Currently delays in the stope turnover occur, this is called stope slippage. This thesis describes the occurrence and size of stope slippage in longhole mining, presents a system to identify and track the root causes of stope slippage and ranks the root causes of stope slippage at Kidd Mine. A flowchart was created to present the system of identifying and ranking root causes of stope slippage.Section Resource EngineeringCivil Engineering and Geoscience

    Volney, 'The ruins' and 'Catechism of natural law'

    No full text
    Volney was once as influential as Tom Paine, and the author of one of the most popular works of the French Revolutionary era. The Ruins makes an argument for popular sovereignty, couched in the alluring and accessible form of an Oriental dream-tale. A favourite of both Thomas Jefferson, who translated it, and the young Abraham Lincoln, the Ruins advances a scheme of radical, utopian politics premised upon the deconstruction of all the world’s religions. It was widely celebrated by radicals in Britain and America, and exercised an enormous influence on poets from Percy Bysshe Shelley to Walt Whitman for its indictments of tyranny and priestcraft. Volney instead advocates a return to natural precepts shorn of superstition, set out in his sequel, the Catechism of Natural Law. These days Volney enjoys a high profile in African-American Studies as a proponent of Black Egyptianism

    Learning from social interaction: The form and function of relative clauses in discourse and experimental studies with children

    No full text
    According to usage-based and constructivist approaches to language development, linguistic categories and structures have semantic content and a communicative function. Relative clauses (RCs) serve a variety of functions in spoken discourse. Depending on their function, RCs occur in different discourse and linguistic contexts and are marked by different formal, semantic, and lexical features. This has largely been ignored in studies that investigated children’s processing of these complex structures. I will summarize cross-linguistic corpus studies that analyzed the form and function of RC constructions in children’s and adults’ speech. Furthermore, I will summarize findings from recent cross-linguistic experiments that suggest that children’s processing of RC constructions is constrained by the form and function of RCs as they are used in social interactions as well as by the form and function of other related, more frequent constructions. Most of the corpus and experimental data come from children learning English, German, Japanese, or Cantonese because there are comparable studies, but I will also indicate when there is data from other languages

    J.C. Bach's London keyboard sonatas : style and context

    No full text
    J. C. Bach's keyboard works include several sets of accompanied sonatas, a genre that enjoyed a wide popularity during the Classical era, but never found its way into the concert repertoire. The accompanied sonata was a genre meant for domestic performance; the solo keyboard sonata, on the other hand, was adopted in due course by concert audiences. J. C. Bach composed works within both genres during most of his productive years, and his output constitutes a corpus of remarkable consistency. J. C. Bach's removal to London in 1762 coincided with his clear adoption of a galant style, marked by the Italianate influence, and the abandonment of most Baroque traits. The British milieu provided additional factors: the rise of the pianoforte, a thriving music-publishing market, and a great interest in domestic music making among the affluent classes. These factors marked J. C. Bach's output at various levels. Keyboard works had to conform to the proficiency of the amateur performer, a fact reflected in the accompanied output mostly. The number of movements, their length, and the inclusion of particular technical devices are readily observable differences between the two genres. The most remarkable distinction lies perhaps in the preference for binary sonata format in the accompanied. sonatas from the mid 1760s to the 1770s, in spite of a later tendency for tripartite designs in both genres. J. C. Bach's lifelong preference for motivic phrase structure conditioned his keyboard production and partly explains the gap in quality between some of his works and sonatas composed around the same time by Haydn and Mozart, who developed more effective means to connect the melodic material to higher structural units. J. C. Bach's influence, however, endured in Mozart's handling of melody, and his keyboard production constitutes, in spite of some flaws, a noteworthy example of elegance and craftsmanship

    Individual differences in structural priming in children: the influence of perspective-taking.

    No full text
    Abstract. Structural priming refers to reusing the syntactic structure of the interlocutor. Children differ in the extent to which they are primed (primeability). Previous research has suggested that an individual’s level of perspective-taking, i.e., the ability to imagine the feelings, thoughts and perceptions of others (McDonald & Messinger, 2011), predicts the magnitude of priming in adults (Horton, 2014). The present study investigates if this also holds for monolingual and bilingual children. In Experiment 1, we primed the possessive structure in monolingual Dutch children. In Experiment 2, we did the same with a group of bilingual children with varying L2s. In both experiments, there was individual variation in children’s primeability. For both monolingual and bilingual children, we found that the priming effect was predicted by children’s language proficiency and perspective-taking abilities. These findings suggest that structural priming serves a social function which is mediated by perspective-taking abilities

    Biological sex disparities in Alzheimer's disease

    No full text
    Alzheimer's disease is a highly complex and multifactorial neurodegenerative disorder, with age being the most significant risk factor. The incidence of Alzheimer's disease doubles every 5 years after the age of 65. Consequently, one of the major challenges in Alzheimer's disease research is understanding how the brain changes with age. Gaining insights into these changes could help identify individuals who are more prone to developing Alzheimer's disease as they age. Over the past 25 years, studies on brain aging have examined thousands of human brains to explore the neuronal basis of age-related cognitive decline. However, most of these studies have focused on adults over 60, often neglecting the critical menopause transition period. During menopause, women experience a substantial decline in ovarian sex hormone production, with a decrease of about 90% in estrogen levels. Estrogen is known for its neuroprotective effects, and its significant loss during menopause affects various biological systems, including the brain. Importantly, despite known differences in dementia risk between sexes, the impact of biological sex and sex hormones on brain aging and the development of Alzheimer's disease remains underexplored.
