This paper concerns the performance of national war memory at the Changi Chapel and Museum, a site honouring the many prisoners interned in Japanese-Occupied Singapore—especially at Changi—during the Second World War. In the light of the global nature of ‘the Changi story’, and the predominantly transnational nature of its present in situ memorialisation, we first examine how the Singapore state has sought to ‘localise’ the site to make it equally appealing to Singaporeans, as a place where a sense of their ‘shared history’ may be invoked. We then explore the Singaporeans' views about the site and its reconfiguration as a national icon, arguing how the state's task of ‘localising’ the site has been a vexed process due to myriad factors such as ethnic and religious plurality, and the already foreign-centric bias of prevailing knowledge about Changi. Following that, we show how this performance of national memory is also inflected by Australia's national remembrance of the same event. More broadly, we highlight the contested process of ‘localising’ such war memoryscapes as national iconography, suggesting how it may be more fruitful to conceive them as ‘international memoryscapes’, or places to which all individuals can relate regardless of race or national affiliations. 相似文献

This article examines Indonesian-Malaysian relations in the light of Indonesia's new archipelagic regime. Archipelagos are defined and the rights and duties of archipelagic states under the Law of the Sea Convention are outlined. Indonesian-Malaysian relations from the 1974 Memorandum of Understanding to the 1982 bilateral treaty are described. The author examines the implications of an Indonesian suspension of passage on Malaysian transport, submarine cables and pipelines, fishing, oil and gas, and search and rescue. The author concludes by indicating how the two countries should adjust to the regime. 相似文献

Salinity mapping of coastal groundwater aquifers using hydrogeochemical and geophysical methods: a case study from north Kelantan,Malaysia 总被引：2，自引：0，他引：2
Integrated hydrogeochemical and geophysical methods were used to study the salinity of groundwater aquifers along the coastal
area of north Kelantan. For the hydrogeochemical investigation, analysis of major ion contents of the groundwater was conducted,
and other chemical parameters such as pH and total dissolved solids were also determined. For the geophysical study, both
geoelectrical resistivity soundings and reflection seismic surveys were conducted to determine the characteristics of the
subsurface and groundwater contained within the aquifers. The pH values range from 6.2 to 6.8, indicating that the groundwater
in the study area is slightly acidic. Low content of chloride suggests that the groundwater in the first aquifer is fresh,
with an average concentration of about 15.8 mg/l and high geoelectrical resistivity (>45 ohm m). On the other hand, the groundwater
in the second aquifer is brackish, with chloride concentration ranging from 500 mg/l to 3,600 mg/l and very low geoelectrical
resistivity (<45 ohm m) as well as high concentration of total dissolved solids (>1,000 mg/l). The groundwater in the third
aquifer is fresh, with chloride concentrations generally ranging from 2 mg/l to 210 mg/l and geoelectrical resistivity of
greater than 45 ohm m. Fresh and saltwater interface in the first aquifer is generally located directly in the area of the
coast, but, for the second aquifer, both hydrogeochemical and geoelectrical resistivity results indicate that the fresh water
and saltwater interface is located as far as 6 km from the beach. The considerable chloride ion content initially suggests
that the salinity of the groundwater in the second aquifer is probably caused by the intrusion of seawater. However, continuous
monitoring of the chloride content of the second aquifer indicated no significant changes with time, from which it can be
inferred that the salinity of the groundwater is not affected by seasonal seawater intrusion. Schoeller diagrams illustrate
that sulphate concentrations of the groundwater of the second aquifer are relatively low compared to those of the recent seawater.
Therefore, this result suggests that the brackish water in the second aquifer is probably from ancient seawater that was trapped
within the sediments for a long period of time, rather than due to direct seawater intrusion. 相似文献

Groundwater investigation in Kuala Selangor using vertical electrical sounding (VES) surveys 总被引：2，自引：0，他引：2
Integrated geoelectrical and hydrochemical surveys were used to investigate and delineate different types of groundwater in
the Kuala Selangor alluvial aquifer. Previous hydrogeological borehole investigation showed that this aquifer contains several
types of groundwater in relation to its salinity. The high salinity of the groundwater in some areas is believed to be due
to either saltwater intrusion from the nearby sea or river infiltration during high tide season. The vertical electrical sounding
(VES) method was employed to study and map the subsurface variation of resistivity in the area. For each sounding measurement,
a total spread length of 300 m was obtained with a vertical depth penetration of about 60 to 75 m. Chemical analysis of the
groundwater samples taken from both shallow and deep boreholes was carried out for the water quality determination. A total
of 45 VES stations were succesfully established along three parallel roads with a direction almost perpendicular to the coastal
line. The distance between stations varies from 1 to 2 km with a maximum length of about 60 km surveyed line. Results of the
vertical electrical soundings as well as the hydrochemistry of the groundwater samples show that the soil and groundwater
in the study area can be grouped into fresh and brackish water zones. The subsurface resisitivity sections derived from the
VES study suggest that the area is dominated by brackish soil and groundwater zones, especially in the area towards the coast.
This result appears to agree well with the groundwater pumped from boreholes scattered around in the area. Water drawn from
boreholes near the coast showed higher salinity compared to the water pumped from inland boreholes. Chloride values greater
than 250 mg/L are considered to represent the brackish zones whilst values less than 250 mg/L represents zones of fresh soil
and groundwater. 相似文献

Extensive agricultural, residential, and industrial activities have increased demand for water supplies, which can lead to groundwater quality degradation. The integration of geochemical methods, multivariate statistical analysis, and geostatistical approaches were carried out on 169 groundwater samples to elucidate the regional factors and processes that influencing the geochemical composition of groundwater in coastal shallow aquifer of Terengganu, Malaysia. Hydrochemical modelling revealed that the abundance of Ca and Mg was contributed by carbonate and silicate weathering while higher HCO3 and Cl were resulted from reverse ion exchange reaction. Therefore, the dominant hydrogeochemical facies of groundwater was Ca-Mg-HCO3-Cl type. The influence of salinization resulting from seawater mixing to the groundwater was corroborated by Cl/HCO3 ratio, which affected around 50.9% of the groundwater samples slightly or moderately. Spatial mapping using ordinary kriging found that the threat of sea water intrusion is more prominent in the major river confluence especially around Terengganu and Marang River in the northeast and Dungun and Kemaman River confluence in southeast of study area. Moreover, factor analyses concluded that salinization, anthropogenic activities, reverse ion exchange, weathering processes, agricultural impact, and seasonal variations were the factors that regulate 63% of the major ion chemistry in study area. Finally, these findings showed the importance of understanding the hydrochemical characteristics for effective utilization, aquifer protection, and prediction of changes to minimize the effects of salinization and reduce human pollution such as agriculture and urbanization. It is essential steps in order to safeguard the utilization of groundwater resources for future generations. 相似文献

The 2010 Mentawai earthquake (magnitude 7.7) generated a destructive tsunami that caused more than 500 casualties in the Mentawai Islands, west of Sumatra, Indonesia. Seismological analyses indicate that this earthquake was an unusual “tsunami earthquake,” which produces much larger tsunamis than expected from the seismic magnitude. We carried out a field survey to measure tsunami heights and inundation distances, an inversion of tsunami waveforms to estimate the slip distribution on the fault, and inundation modeling to compare the measured and simulated tsunami heights. The measured tsunami heights at eight locations on the west coasts of North and South Pagai Island ranged from 2.5 to 9.3 m, but were mostly in the 4–7 m range. At three villages, the tsunami inundation extended more than 300 m. Interviews of local residents indicated that the earthquake ground shaking was less intense than during previous large earthquakes and did not cause any damage. Inversion of tsunami waveforms recorded at nine coastal tide gauges, a nearby GPS buoy, and a DART station indicated a large slip (maximum 6.1 m) on a shallower part of the fault near the trench axis, a distribution similar to other tsunami earthquakes. The total seismic moment estimated from tsunami waveform inversion was 1.0 × 1021 Nm, which corresponded to Mw 7.9. Computed coastal tsunami heights from this tsunami source model using linear equations are similar to the measured tsunami heights. The inundation heights computed by using detailed bathymetry and topography data and nonlinear equations including inundation were smaller than the measured ones. This may have been partly due to the limited resolution and accuracy of publically available bathymetry and topography data. One-dimensional run-up computations using our surveyed topography profiles showed that the computed heights were roughly similar to the measured ones. 相似文献

A geophysical study was carried out in the Banting area of Malaysia to delineate groundwater aquifer and marine clay layer
of the alluvial Quaternary deposits of Beruas and Gula Formations. The Beruas Formation is formed by peat and clayey materials
as well as silt and sands, whereas the Gula Formation consists of clay, silt, sand and gravels. Both Formations were deposited
on top of the Carboniferous shale of the Kenny Hill Formation. A 2-D geoelectrical resistivity technique was used. Resistivity
measurement was carried out using an ABEM SAS 4000 Terrameter. The 2-D resistivity data of subsurface material for each survey
line was calculated through inverse modelling and then compared with borehole data. The resistivity images of all the subsurface
material below the survey lines show similar pattern of continuous structure of layering or layers with some lenses with resistivity
ranging from 0.1 to 50 Ωm. The upper layer shows resistivity values ranging from 0.1 to 10 Ωm, representing a clay horizon
with a thickness up to 45 m. The second layer with depth varies from 45 to 70 m below surface and has resistivity values ranging
from 10 to 30 Ωm. Borehole data indicate coarse sand with some gravels for this layer, which is also the groundwater aquifer
in the study area. The lowermost layer at a depth of 70 m below ground level shows resistivity values ranging from 30–50 Ωm
and can be correlated with metasedimentary rocks consisting of shale and metaquartzite. 相似文献

Despite the salience of the Second World War in paving the way for Singapore to attain formal independent status in 1965,
it was not until the 1990s that war events were inserted into the state’s narratives, and ‘mapped’ onto its spaces as visible
national fodder to bind citizens together. Since then, memoryscapes in many forms have proliferated over the state’s cityscape.
After tracing the genesis of official war commemorative gestures within Singapore, the paper examines the ways in which Singaporeans
have responded to them. Specifically, the paper argues that, while Singaporeans recognize the importance of remembering the
war as nationally significant, this has not translated into any physical attempt or desire—beyond the discursive—to participate
in the state’s commemorative endeavours. In analyzing factors that may have hindered the actual bodily practice of war remembrance in Singapore, nationalized war memoryscapes are also seen as embodying numerous politics due
to tensions arising from a collision between what the state and its people perceive to be ideal means of remembering and representing
the war within national discourses in the context of the present. 相似文献

Summary This paper considers the propagation of a progressive tidal wave along a canal of uniform width, in which the depth increases linearly from one side to the other. The linearised tidal equations are solved firstly by a perturbation procedure for small inclinations of the bed to the horizontal, and secondly by a numerical method from the exact solution, for some particular values of the parameters. 相似文献
