This article explores the ways that parental death represents a ‘vital conjuncture’ for Serer young people that reconfigures and potentially transforms intergenerational caring responsibilities in different spatial and temporal contexts. Drawing on semi-structured interviews with young people (aged 15–27 years), family members, religious and community leaders and professionals in rural and urban Senegal, I explore young people's responses to parental death. ‘Continuing bonds’ with the deceased were expressed through memories evoked in homespace, shared family practices and gendered responsibilities to ‘take care of’ bereaved family members, to cultivate inherited farmland and to fulfil the wishes of the deceased. Parental death could reconfigure intergenerational care and lead to shifts in power dynamics, as eldest sons asserted their position of authority. While care-giving roles were associated with agency, the low social status accorded to young women's paid and unpaid domestic work undermined their efforts. The research contributes to understandings of gendered nuances in the experience of bereavement and continuing bonds and provides insight into intra-household decision-making processes, ownership and control of assets. Analysis of the culturally specific meanings of relationships and a young person's social location within hierarchies of gender, age, sibling birth order and wider socio-cultural norms and practices is needed. 相似文献

Ongoing (1996–present) volcanic unrest near South Sister, Oregon, is accompanied by a striking set of hydrothermal anomalies, including elevated temperatures, elevated major ion concentrations, and 3He/4He ratios as large as 8.6 RA in slightly thermal springs. These observations prompted the US Geological Survey to begin a systematic hydrothermal‐monitoring effort encompassing 25 sites and 10 of the highest‐risk volcanoes in the Cascade volcanic arc, from Mount Baker near the Canadian border to Lassen Peak in northern California. A concerted effort was made to develop hourly, multiyear records of temperature and/or hydrothermal solute flux, suitable for retrospective comparison with other continuous geophysical monitoring data. Targets included summit fumarole groups and springs/streams that show clear evidence of magmatic influence in the form of high 3He/4He ratios and/or anomalous fluxes of magmatic CO2 or heat. As of 2009–2012, summit fumarole temperatures in the Cascade Range were generally near or below the local pure water boiling point; the maximum observed superheat was <2.5°C at Mount Baker. Variability in ground temperature records from the summit fumarole sites is temperature‐dependent, with the hottest sites tending to show less variability. Seasonal variability in the hydrothermal solute flux from magmatically influenced springs varied from essentially undetectable to a factor of 5–10. This range of observed behavior owes mainly to the local climate regime, with strongly snowmelt‐influenced springs and streams exhibiting more variability. As of the end of the 2012 field season, there had been 87 occurrences of local seismic energy densities approximately ≥ 0.001 J/m3 during periods of hourly record. Hydrothermal responses to these small seismic stimuli were generally undetectable or ambiguous. Evaluation of multiyear to multidecadal trends indicates that whereas the hydrothermal system at Mount St. Helens is still fast‐evolving in response to the 1980–present eruptive cycle, there is no clear evidence of ongoing long‐term trends in hydrothermal activity at other Cascade Range volcanoes that have been active or restless during the past century (Baker, South Sister, and Lassen). Experience gained during the Cascade Range hydrothermal‐monitoring experiment informs ongoing efforts to capture entire unrest cycles at more active but generally less accessible volcanoes such as those in the Aleutian arc. 相似文献

A group of 400–500 m long, bedding‐parallel calcite veins are exposed in the central La Popa Basin of northeastern Mexico. These veins provide a unique opportunity to determine the kilometer‐scale fluid–rock system associated with bedding‐parallel vein formation, and to test for sampling bias in studies that often use one or two samples to constrain the characteristics of regional‐scale paleohydrogeological systems. We use fluid inclusion microthermometry in conjunction with measurements of δ13C, δ18O, and 87Sr/86Sr ratios to constrain the vein‐forming fluid temperatures, compositions and sources, and compare these values along and between the veins to establish the homogeneity of the vein‐forming fluids and fluid–rock system. The δ13C values of the veins are close to those of the host rock, and average – 3.96‰ (PDB). The δ18O values of the veins are typically 1‰ lower than those of the host rocks, and average – 9.54‰ (PDB). Fluid inclusion homogenization temperatures average 137°C and inclusion salinities are all <6 wt% NaCl equivalent. The 87Sr/86Sr ratios of the veins average 0.70731 and are substantially lower than the values expected for the host rock. Calculated fluid δ18O values range from 4 to 10‰ (SMOW). The isotopic and microthermometric data indicate the veins most likely formed at depths of 3–4 km when meteoric water mixed with upward migrating, warm basinal brines. Vein microstructures and field characteristics indicate they formed from multiple slip events that most likely were associated with transport of individual fluid pulses that migrated along bedding planes. The large‐scale homogeneity of vein geochemistry is remarkable and demonstrates that only one or two samples would be sufficient to accurately characterize the kilometer‐scale paleohydrogeological system for these veins. 相似文献

The natural wonders listed in the folk history known as the Historia Brittonum include Lake Liuan/Lliwan, the site of which is now lost despite featuring in folktales and topographies and containing a dramatic tidal whirlpool/fountain. We identify this key early-medieval wonder as the Whirlyholes, now inactive features near Caerwent, South Wales. 相似文献

During the 1920s emigration from Scotland exceeded the natural growth of population. Yet relatively little attention has been paid to the mechanisms of relocation, the regional and occupational origins and destinations of the emigrants or their demographic profile. This article draws on the recently compiled Scottish Emigration Database to provide a quantitative snapshot of the circumstances of 18,512 passengers who embarked on the lower Clyde in the first four months of 1923. The first section explains the rationale, methodology and historiographical context of the database. Then, after outlining the economic, social and political climate in inter-war Scotland, the article investigates the extent to which decay, dislocation and disillusionment – or alternatively opportunity and ambition – provoked transatlantic emigration. Reference is made to local and regional issues within Scotland, notably in the urban-industrial central belt and the crofting communities of the Hebrides. Setting the Scottish experience within the wider framework of British emigration policy between the wars, it also evaluates the effectiveness of empire settlement legislation in recruiting and retaining settlers for Canada against the competing attractions of the United States. 相似文献

The accuracy of Miles' method of ageing individuals within a population, based upon an analysis of the rate of dental wear, was evaluated in a sample of 202 living Lengua Indians from the Chaco area of Paraguay. The preliterate and culturally isolated status of the Lengua provided a useful base for comparison with populations that are likely to be encountered by archaeologists. The independent age estimates from maxillae and mandibles of the same individuals were found to be highly correlated with each other and to the actual ages of those individuals (Spearman rank-correlation test maxillae rs = 0·58, mandibles rs = 0·95, medians of populations rank-sum R = 99·5 > 95). No significant differences (P > 0·05) were found between the mean ages of any of the Miles subgroups, as indicated by the t-test for paired comparisons. The present study provides evidence of the reliability of the Miles method of ageing archaeological populations on the basis of occlusal wear. These findings are evaluated in the light of the sources of error inherent in the Miles system of analysis. 相似文献
