TL;DR: Greater use of the Internet was associated with declines in participants' communication with family members in the household, declines in the size of their social circle, and increases in their depression and loneliness.
Abstract: The Internet could change the lives of average citizens as much as did the telephone in the early part of the 20th century and television in the 1950s and 1960s. Researchers and social critics are debating whether the Internet is improving or harming participation in community life and social relationships. This research examined the social and psychological impact of the Internet on 169 people in 73 households during their first 1 to 2 years on-line. We used longitudinal data to examine the effects of the Internet on social involvement and psychological well-being. In this sample, the Internet was used extensively for communication. Nonetheless, greater use of the Internet was associated with declines in participants' communication with family members in the household, declines in the size of their social circle, and increases in their depression and loneliness. These findings have implications for research, for public policy and for the design of technology.

TL;DR: This article analyzed longitudinal data from a field trial of 229 individuals in 110 households during their first year on the Internet and found that interpersonal communication is a stronger driver of Internet use than are information and entertainment applications.
Abstract: The Internet has been characterized as a superhighway to information and as a high-tech extension of the home telephone. How are people really using the Internet? The history of previous technologies that support interpersonal communication suggests that communication may be a more important use and determinant of participants’ commitment to the Internet than is information acquisition and entertainment. Operationalizing interpersonal communication as the use of electronic mail and information acquisition and entertainment as the use of the World Wide Web, we analyzed longitudinal data from a field trial of 229 individuals in 110 households during their first year on the Internet. The results show that interpersonal communication is a stronger driver of Internet use than are information and entertainment applications.

TL;DR: The aim is to demonstrate how perspicuous accounts of precomputation and frequency reduction can be given for a wide range of applications using a small number of relatively straightforward techniques.
Abstract: Computations can generally be separated into stages, which are distinguished from one another by either frequency of execution or availability of data. Precomputation and frequency reduction involve moving computation among a collection of stages so that work is done as early as possible (so less time is required in later steps) and as infrequently as possible (to reduce overall time).We present, by means of examples, several general transformation techniques for carrying out precomputation transformations. We illustrate the techniques by deriving fragments of simple compilers from interpreters, including an example of Prolog compilation, but the techniques are applicable in a broad range of circumstances. Our aim is to demonstrate how perspicuous accounts of precomputation and frequency reduction can be given for a wide range of applications using a small number of relatively straightforward techniques.Related work in partial evaluation, semantically directed compilation, and compiler optimization is discussed.

TL;DR: In this paper, a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) is presented.
Abstract: Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

TL;DR: In this comprehensive social theory of the Internet and the networked information economy, Benkler describes how patterns of information, knowledge, and cultural production are changing--and shows that the way information and knowledge are made available can either limit or enlarge the ways people can create and express themselves.
Abstract: With the radical changes in information production that the Internet has introduced, we stand at an important moment of transition, says Yochai Benkler in this thought-provoking book. The phenomenon he describes as social production is reshaping markets, while at the same time offering new opportunities to enhance individual freedom, cultural diversity, political discourse, and justice. But these results are by no means inevitable: a systematic campaign to protect the entrenched industrial information economy of the last century threatens the promise of today's emerging networked information environment. In this comprehensive social theory of the Internet and the networked information economy, Benkler describes how patterns of information, knowledge, and cultural production are changing--and shows that the way information and knowledge are made available can either limit or enlarge the ways people can create and express themselves. He describes the range of legal and policy choices that confront us and maintains that there is much to be gained--or lost--by the decisions we make today.
