Objective:
Cognitive screening tools such as the Montreal Cognitive Assessment (MoCA) play an essential role in the clinical evaluation of neuropsychological functions. Despite the extensive investigations of the MoCA in English speaking countries as well as emerging adaptation work in a few Asian cultures, evidence base for the utility of the Vietnamese MoCA (MoCA-V) is lacking. This has posed a huge challenge for current and future clinical practice in Vietnam, as the country continues to assume a large burden of brain-related disorders. This study examined the construct validity of the MoCA-V and identified a cut-off score for the determination of cognitive impairment in a prevalent neurological condition in Vietnam - traumatic brain injury (TBI).
Participants and Methods:Participants included 129 neurologically healthy individuals and 80 patients with moderate-to-severe TBI. All participants completed the MoCA-V, along with other common neurocognitive measures such as the Trail Making Test (TMT) Parts A and B, Vietnamese Verbal Fluency Test, and Digit Span.
Results:Pearson’s correlations revealed significant, moderate correlations between performance on the MoCA-V subdomains and more comprehensive cognitive measures. Performance on the MoCA-V Attention domain was correlated with both Digit Span Forward, r(110) = .453, p < .001] and Digit Span Backward, r(110) = .303, p = .001; performance on the MoCA Language domain was correlated with the Vietnamese Verbal Fluency Test, r(107) = .334, p < .001; and performance on the MoCA Executive Function domain was correlated with the TMT-B, r(108) = -.479, p = .022. Performance on the MoCA-V was also associated with age, r(127) = -.659, p < .001, and education, r(127) = .769, p < .001, consistent with the general effects of age and education in cognitive abilities. Finally, a cut-off score of 22.5 was identified for the detection of cognitive impairment in Vietnamese people with TBI (AUC = 0.811; 95% CI = .75-.87, p < .001).
Conclusions:This study provides the first evidence for the construct validity and clinical utility of the MoCA-V. Future research is necessary to cross-validate study findings among other clinical populations. Lessons learned from neuropsychological test translation and adaptation process will be discussed, particularly in the development of the administration materials and test instructions (e.g., considerations for individuals with limited formal education, influences of colonialism in the development of test stimuli).

Summary
Previous studies have shown that limits on loan-to-value (LTV) and debt-to-income (DTI) ratios can stabilize the housing market, and that tightening these limits tends to be more effective than loosening them. This paper examines whether the relative effectiveness of tightening versus loosening macroprudential measures depends on where in the housing cycle they are implemented. I find that tightening measures have greater effects when credit is expanding quickly and when house prices are high relative to income. Loosening measures seem to have smaller effects than tightening, but the difference is negligible in downturns. Loosening being found to have small effects is consistent with where it occurs in the cycle.

Rietveld-based quantitative X-ray diffraction (QXRD) has been extensively used for mineralogical characterization in order to understand the reaction chemistry, and kinetics of minerals leaching and formation. This work presents examples where QXRD has been applied to understanding fundamental aspects of these two processes. Firstly, the co-processing of nickel laterites and sulphidic materials has the potential to offer several advantages that include the use of lower grade (including non-smeltable) concentrates, improvement in the rheological behaviour of the blends, and reduction in the use of sulphuric acid. The leaching kinetics and chemistry of mixed nickel laterite ore and sulphide concentrate were explored by the QXRD analysis of feed materials and, intermediates and final leach residues produced using controlled oxidation rates. Under high temperature (250 °C) and pressure oxidation (~40 to 45 atm.) conditions, sulphide minerals in the nickel concentrate underwent several oxidative hydrothermal transformations, and ferrous iron was oxidized and precipitated primarily as hematite. High recovery of nickel can be achieved with low acid consumption under these conditions. Secondly, iron precipitation/removal is an important down-stream process in hydrometallurgy. Moderate concentrations of ferrous iron can be oxidized using micro-organisms with oxidation rates several orders of magnitude faster compared with abiotic oxidation at ambient temperature and pressure. QXRD and chemical analysis have indicated that after oxidation, iron at pH ~2 mostly precipitates as jarosite with various amounts of K+, Na+, NH4+, and H3O+ incorporated into the structure. Bio-catalysed iron removal can be achieved with minimum copper and nickel losses at relatively low pH conditions.

The central rock-rat Zyzomys pedunculatus is categorized as Critically Endangered on the IUCN Red List. Over the last 50 years the species had only been recorded from 14 sites within a 600 km2 area of the West MacDonnell National Park and immediate surroundings in the Northern Territory, Australia. The central rock-rat disappeared from monitoring sites in 2002, coincident with the onset of drought conditions and extensive wildfires. With concern growing for the survival of the species, we sought to locate an extant population. During 2009–2012 we surveyed sites throughout the western sector of the West MacDonnell National Park, including sites where rock-rats had previously been recorded. From a total of 55 sites and 5,000 trap nights we located eight central rock-rats from only five sites (overall detection rate = 0.16 rock-rats per 100 trap nights). All sites were on two mountain-top locations, both of which are over 1,250 m altitude. Evidence of reproductive activity was observed at both locations but the subpopulations were relatively localized and no individuals were captured at any of the sites from which the species was known previous to these surveys. Although the rugged mountains may provide the central rock-rat with some refuge from predation and wildfires, more research is needed to understand better the factors suppressing and constraining the species at the population and landscape scales. Immediate management priorities are prescribed burning to limit the extent and severity of wildfires and trialling a baiting programme with 1080 to target feral cats in the mountains.

Knowledge about the diet of fish-eating predators is critical when evaluating conflicts with the fishing industry. Numerous primary studies have examined the diet of grey seals Halichoerus grypus and common seals Phoca vitulina in a bid to understand the ecology of these predators. However, studies of large-scale spatial and temporal variation in seal diet are limited. Therefore this review combines the results of seal diet studies published between 1980 and 2000 to examine how seal diet varies at a range of spatial and temporal scales. Our results revealed extensive spatial variation in gadiform, perciform and flatfish consumption, likely reflecting variation in prey availability. Flatfish and gadiform consumption varied between years, reflecting changes in fish assemblages as a consequence of factors such as varying fishing pressures, climate change and natural fluctuations in populations. Perciform and gadiform consumption varied seasonally: in addition there was a significant interaction between season and seal species, indicating that grey and common seals exhibited different patterns of seasonal variation in their consumption of Perciformes and Gadiformes. Multivariate analysis of grey seal diet revealed spatial variation at a much smaller scale, with different species dominating the diet in different areas. The existence of spatial and temporal variation in seal diet emphasizes that future assessments of the impact of seal populations should not be based on past or localized estimates of diet and highlights the need for up-to-date, site specific estimates of diet composition in the context of understanding and resolving seal/fisheries conflict.

Three modern speleothems were sampled at high resolution for radiocarbon analysis to identify their bomb-pulse signatures and to construct chronologies. Each speleothem exhibited a different 14C response, presumed to be related to site characteristics such as vegetation, temperature, rainfall, depth below the surface, and water pathway through the aquifer. Peak 14C activity for WM4 is 134.1 pMC, the highest cited thus far in the literature and suggestive of a lower inertia at this site. Dead carbon fractions for each stalagmite were calculated and found to be relatively similar for the 3 speleothems and lower than those derived from Northern Hemisphere speleothems. An inverse modeling technique based on the work of Genty and Massault (1999) was used to estimate soil carbon residence times. For each speleothem, mean soil 14C reservoir ages differed greatly between the 3 sites, ranging from 2–6.5 to 32–46 yr.

Introduction
The concern of this article is with a particular set of harmonic practices that rock musicians, particularly those who participate in the domain of guitar-oriented ‘alternative’ rock, have been using with noticeable frequency in the last ten years. I am also interested in discussing the concept of the power chord (a term I shall explicate more clearly below) as a device in rock that has facilitated the above-mentioned set of harmonic practices
The observations made in this paper come out of a previous research inquiry of mine into the devices which alternative musicians use to differentiate their music from other styles of mainstream rock. Also, the pursuit of this topic is partly a response to Allan Moore's admonition that ‘there is as yet very little concern for theorizing analytical method in rock music’, and his call for a ‘mapping-out of those harmonic practices that serve to distinguish rock styles . . . from those of common-practice tonality . . . and jazz’ (Moore 1995, p. 185).
There has been some rather pointed criticism recently of musicological analyses of popular music (see Shepherd 1993; Frith 1990) on the charge that analysing music's purely sonic dimensions (i.e. melody, harmony, rhythm, structure, etc.) does not really help us understand musical communication. Speaking as a songwriter, however, I would argue that many musicians in rock are indeed concerned with harmonic progression (or ‘the changes’, to use the vernacular term) as an important device or jumping-off point in the process of songwriting. It also seems reasonable to suggest that harmonic progression is a contributing factor in the affective power of a song, although its importance here is likely to be variable and quite open to debate.

Summary
While the details of climate change and global warming remain subjects of intense debate, there is a growing awareness that the earth's temperature regime is changing, as a result of either natural variation or anthropogenic emissions of ‘greenhouse gases’. The effects of warming scenarios on agriculture, human health and vegetation have been extensively studied over the past decade, but there has been remarkably little research on the anticipated effects on fish and fisheries. This is somewhat surprising, given the fact that temperature is undoubtedly the most thoroughly studied environmental variable in fish biology! Fish are poikilotherms living in a medium of high heat capacity and conductance; their body temperature is normally within a few fractions of a degree of the water, and therefore the rates of all of their biological functions are critically dependent on environmental temperature.
A few years ago, as we started our own research programme in this area, we came to realize that there existed only a modest amount of information on the long-term effects of small temperature increments on fish. Nonetheless, there was also clearly available a wealth of classical data on ‘temperature effects’ from which extrapolation and speculation could be made. We thought it would be useful to bring together experts from all areas of fish biology, and ask them to summarize the existing information, to identify significant gaps in current understanding, and to speculate, based on their knowledge of the field, on the responses of fish to chronic small increments in temperature superimposed on natural regimes.
