This chapter examines the use of information and communication technologies (ICTs) by Mexican immigrant families living in the United States to care for their aged left-behind parents and grandparents suffering from poor health. It introduces the concepts of ‘rescue chain’ and ‘care talk’ to account for the interplay between ICTs and transnational families. Drawing on the stories of ten participants, the chapter considers how Mexican immigrants and their siblings, locally and abroad, form rescue chains to deliver care to ageing left-behind parents with health problems through ICTs. It shows that the rescue chain communication involves care talk that focused on protecting, providing, and proving that the care needs of the person in crisis were addressed. The chapter also reviews the literature on ageing and long-distance caring through ICTs, discusses theories on care and ageing, and explains the methodology and sources used in the study.

ABSTRACTIn 1939 Dr Thomas C. Poulter, Director of the Armour Institute, Chicago and a veteran of Byrd's second Antarctic expedition, designed and constructed a 30 tonne wheeled vehicle known as the Snow Cruiser for use with the US Antarctic Service Expedition. Designed for self-contained long-distance travel, the vehicle had many new features including twin diesel engines, independent electric drive and steering on each of its four wheels, and a light aircraft carried on the roof. It was built in Chicago and tested briefly on sand dunes nearby, before being driven to Boston amid much public interest for shipment to Antarctica. At the Bay of Whales the vehicle quickly became bogged down in snow, and never moved farther south than the expedition's winter quarters. Modern evaluation of wheel-snow interaction suggests that the Snow'Cruiser unladen was three to five times too heavy for its tyres to support it on snow surfaces. It was nevertheless a bold attempt to push forward the frontiers of mobility in exploration, which failed in a spectacular fashion. The vehicle was left behind when the expedition returned home, and has subsequently been lost.

Urbanization is the process that people shift from rural to urban areas, which has led to large numbers of left-behind children in China. The left-behind children stay in rural regions of China while their parents work in urban areas. The left-behind children have few opportunities to participate in sports due to the lacking of concern, and it is not of high quality even though they participate in sports. Therefore, it is necessary to improve the quality of left-behind children's sports participation through wireless network monitoring. Wireless network monitoring transmits high-definition (HD) video streaming in real time to facilitate feedback timely. This paper studies the two-dimensional (2D) integer discrete cosine transform (DCT) and analyzes the reason for image distortion, then an improved DCT coefficient quantization approach is proposed for long-distance real-time transmission of HD video streaming, and a noise processing with a zero-mean noise processing is added in optimized approach to solve the image distortion problem. The experimental results show that the proposed improved approach has a good performance in reducing the blocking artifacts, and within the image reconstruction, the proposed approach improves the subjective video quality.

Historians have approached the Indian Ocean from a variety of vantages in their attempts to explain the modern history of this huge maritime arena. Some scholars have concentrated on predation as a linking theme, charting how piracy connected a broad range of actors for centuries in these dangerous waters. Others have focused on environmental issues, asking how patterns of winds, currents, and weather allowed trade to flourish on such a vast, oceanic scale. These latter historians have appropriated a page out of Braudel, and have grafted his approaches to the Mediterranean to fit local, Indian Ocean realities, such as the role of cyclones and mangrove swamps in both helping and hindering long-distance commerce. Still other scholars have used different tacks, following trails of commodities such as spices or precious metals, or even focusing on far-flung archaeological remains, in an attempt to piece together trans-regional histories from the detritus civilisations left behind. All of these epistemological vectors have shed light on the region as a whole, though through different tools and lenses, and via a variety of techniques of inquiry.

Abstract We study health selection in rural–urban migration in Finland using register data. Specifically, we ask whether ‘movers’ differ from ‘stayers’ in their use of special health care services prior to moving. We focus on migration to twelve growing urban centres in different sub-groups of the population as well as in different regions, using multinomial logistic regression and multilevel modelling and by distinguishing between short- and long-distance moves. The results show that urban centres attract healthier individuals, while people with health problems are also prone to move, but not to urban centres. The results were similar when looking only at psychiatric diagnoses. The findings suggest that it is important to distinguish between different types of moves when studying health-selective migration. Studying the patterns of migration according to health enables us to understand drivers of regional health differences. Moreover, such evidence will help in projecting future demand for healthcare across the country.

The Philippines is an intensely migrant society with an annual migration of one million people, leading to over a tenth of the population working abroad. Many of these emigrants are mothers who often have children left behind. Family separation is now recognized as one of the social costs of migration affecting the global south. Relationships within such transnational families depend on long-distance communication and there is an increasing optimism among Filipino government agencies and telecommunications companies about the consequences of mobile phones for transnational families. This article draws on comparative research with UK-based Filipina migrants — mainly domestic workers and nurses — and their left-behind children in the Philippines. Our methodology allowed us to directly compare the experience of mothers and their children. The article concludes that while mothers feel empowered that the phone has allowed them to partially reconstruct their role as parents, their children are significantly more ambivalent about the consequences of transnational communication.

Chapter 4 reveals that maintaining relationships between parents and children, though challenging, paled in comparison to the work needed to keep alive passionate romantic relationships between male migrants and the female partners they left behind. This chapter focuses on the on again, off again relationship between José’s younger brother, Paco, and Conchita’s older sister, Chifis or Chonita. It demonstrates that the rudimentary systems of communication, distance, rampant chisme, and shifting interests and personal goals proved too burdensome for them to maintain a long-term, long-distance courtship. Though the noviasgo (courtship) did not result in marriage, it allowed them to express their greatest hopes and dreams as well as their everyday social and cultural experiences across the vast divide. While letters often worked to maintain and build relations, this chapter shows how and why they worked to destroy them as well.

By focusing on the relations of intimacy between migrant wives working in Singapore and their left-behind husbands living in the Philippines, this article investigates how transnational couples negotiate the liminalities and temporariness embedded in the experience of labour migration. Using the timescales of migration as a conceptual frame, the article analyses the mutual, if uneven, shaping of marital relationships at the micro-timescale of transnational family time and the meso-timescale of Singapore’s labour migration regime. It focuses on how ‘doing family’ across distance is centrally facilitated through the affordances of communication technologies to create rhythms and manage ruptures. These technologies are crucial in (re)making domestic family time in the transnational household. The way the micro-temporalities of transnational family life are reorganised works in tension with how couples negotiate liminal conditions imposed by Singapore’s work permit and pass system. The article argues that temporariness and precarity, which deter the imagination of a stable future, are constantly negotiated in the lives of the transnational family through different temporal strategies. By bracketing off intense emotions and downplaying ruptures in relationships, the transnational family is able to focus on their future aspirations of achieving their projects through migration. As migration timelines are indefinitely extended and family separation is prolonged, the transnational family strives to endure through these strategies of (re)making their temporalities.

Long distance transport in plants takes place in phloem tissue which has characteristic cells, the sieve elements. At maturity these cells have sieve areas in their end walls with specialized perforations. They are associated with companion cells, parenchyma cells, and in some species, with transfer cells. The protoplast of the functioning sieve element contains a high concentration of sugar, and consequently a high hydrostatic pressure, which makes it extremely difficult to fix mature sieve elements for electron microscopical observation without the formation of surge artifacts. Despite many structural studies which have attempted to prevent surge artifacts, several features of mature sieve elements, such as the distribution of P-protein and the nature of the contents of the sieve area pores, remain controversial.
