title: Cross-cultural differences on work-to-family conflict and role satisfaction: A Taiwanese-British comparison

authors: Lu, Luo

subjects: work-to-family conflict (WFC)

abstract: The aim of this research was to explore relations between work and family demands and resources, work-to-family conflict (WFC), and work and family outcomes in a cross-cultural comparative context involving Taiwanese and British employees. Two-hundred and sixty-four Taiwanese employees and 137 British employees were surveyed using structured questionnaires. For both Taiwanese and British employees, work and family demands were positively related to WFC, whereas work resources were negatively related to WFC. Furthermore, WFC was negatively related to family satisfaction. More importantly, we found that nation moderated relationships between work resources and WFC, WFC and work, and family satisfaction. Specifically, work resources had a stronger protective effect for Taiwanese than British in reducing WFC, whereas WFC had a stronger detrimental effect on role satisfaction for British than Taiwanese. It is recommended that both culture-general and culture-specific effects should be taken into consideration in designing future WFC research and familyfriendly managerial practices.

title: Correlating tephras and cryptotephras using glass compositional analyses and numerical and statistical methods: review and evaluation

authors: Lowe, David J.

subjects: Tephra

abstract: We define tephras and cryptotephras and their components (mainly ash-sized particles of glass ± crystals in distal deposits) and summarize the basis of tephrochronology as a chronostratigraphic correlational and dating tool for palaeoenvironmental, geological, and archaeological research. We then document and appraise recent advances in analytical methods used to determine the major, minor, and trace elements of individual glass shards from tephra or cryptotephra deposits to aid their correlation and application. Protocols developed recently for the electron probe microanalysis of major elements in individual glass shards help to improve data quality and standardize reporting procedures. A narrow electron beam (diameter ~3-5 μm) can now be used to analyze smaller glass shards than previously attainable. Reliable analyses of ‘microshards’ (defined here as glass shards <32 µm in diameter) using narrow beams are useful for fine-grained samples from distal or ultra-distal geographic locations, and for vesicular or microlite-rich glass shards or small melt inclusions. Caveats apply, however, in the microprobe analysis of very small microshards (<=~5 µm in diameter), where particle geometry becomes important, and of microlite-rich glass shards where the potential problem of secondary fluorescence across phase boundaries needs to be recognised. Trace element analyses of individual glass shards using laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS), with crater diameters of 20 μm and 10 μm, are now effectively routine, giving detection limits well below 1 ppm. Smaller ablation craters (<10 μm) can be subject to significant element fractionation during analysis, but the systematic relationship of such fractionation with glass composition suggests that analyses for some elements at these resolutions may be quantifiable. In undertaking analyses, either by microprobe or LA-ICP-MS, reference material data acquired using the same procedure, and preferably from the same analytical session, should be presented alongside new analytical data. 
In part 2 of the review, we describe, critically assess, and recommend ways in which tephras or cryptotephras can be correlated (in conjunction with other information) using numerical or statistical analyses of compositional data. Statistical methods provide a less subjective means of dealing with analytical data pertaining to tephra components (usually glass or crystals/phenocrysts) than heuristic alternatives. They enable a better understanding of relationships among the data from multiple viewpoints to be developed and help quantify the degree of uncertainty in establishing correlations. In common with other scientific hypothesis testing, it is easier to infer using such analysis that two or more tephras are different rather than the same. Adding stratigraphic, chronological, spatial, or palaeoenvironmental data (i.e. multiple criteria) is usually necessary and allows for more robust correlations to be made. A two-stage approach is useful, the first focussed on differences in the mean composition of samples, or their range, which can be visualised graphically via scatterplot matrices or bivariate plots coupled with the use of statistical tools such as distance measures, similarity coefficients, hierarchical cluster analysis (informed by distance measures or similarity or cophenetic coefficients), and principal components analysis (PCA). Some statistical methods (cluster analysis, discriminant analysis) are referred to as ‘machine learning’ in the computing literature. The second stage examines sample variance and the degree of compositional similarity so that sample equivalence or otherwise can be established on a statistical basis. This stage may involve discriminant function analysis (DFA), support vector machines (SVMs), canonical variates analysis (CVA), and ANOVA or MANOVA (or its two-sample special case, the Hotelling two-sample T² test). Randomization tests can be used where distributional assumptions such as multivariate normality underlying parametric tests are doubtful.
Compositional data may be transformed and scaled before being subjected to multivariate statistical procedures including calculation of distance matrices, hierarchical cluster analysis, and PCA. Such transformations may make the assumption of multivariate normality more appropriate. A sequential procedure using Mahalanobis distance and the Hotelling two-sample T² test is illustrated using glass major element data from trachytic to phonolitic Kenyan tephras. All these methods require a broad range of high-quality compositional data which can be used to compare ‘unknowns’ with reference (training) sets that are sufficiently complete to account for all possible correlatives, including tephras with heterogeneous glasses that contain multiple compositional groups. Currently, incomplete databases are tending to limit correlation efficacy. The development of an open, online global database to facilitate progress towards integrated, high-quality tephrostratigraphic frameworks for different regions is encouraged.

title: Maori thinking with a dead white male: Philosophizing in the realm of Novalis

authors: Mika, Carl Te Hira

subjects: Novalis

abstract: In this paper I shall discuss my experiences of referring to Novalis in the context of Maori postcolonialism and metaphysical philosophy. As with other methods of research, from a Maori perspective one always alights on and then carries the effects of the philosopher that stands behind the method, whether the philosopher is silent or explicit. This important onto-epistemological interaction, in a general sense, acknowledges for the indigenous person that one is always ‘within’ the world and not detached from it. The maligned dead white male hence unavoidably becomes the highly constructive, living impulse behind what is to become fresh and innovative indigenous thinking.
