The Internet, children, and privacy: the case against parental monitoring

It has been recommended that parents should monitor their children’s Internet use, including what sites their children visit, what messages they receive, and what they post. In this paper, I claim that parents ought not to follow this advice, because to do so would violate children’s right to privacy over their on-line information exchanges. In defense of this claim, I argue that children have a right to privacy from their parents, because such a right respects their current capacities and fosters their future capacities for autonomy and relationships.     

Germs in space. Joshua Lederberg,exobiology, and the public imagination, 1958-1964

Under the leadership of Joshua Lederberg, some American biologists and chemists proposed exobiology as the most legitimate program for space research. These scientists used the fear of contamination--of earth and other planets--as a central argument for funding "nonpolitical," "scientifically valid" experiments in extraterrestrial life detection. Exobiology's resemblance to popular science fiction narratives presented a significant challenge to its advocates' scientific authority. Its most practical applications, moreover, bore an unseemly resemblance to the United States Army's research on biological weapons. At the same time that exobiologists wanted to use the media to attract support for their program, they had to monitor their statements carefully in order to maintain their view of exobiology as a peaceful, scientifically valid research program. In examining how exobiology's creators positioned their work in comparison to other space sciences as well as science fiction, this case study highlights how cultural and political imperatives entered science through practice and narrative during the Cold War.     

Scientific biography, cognitive deficits, and laboratory practice. James McKeen Cattell and early American experimental psychology, 1880-1904

Despite widespread interest in individual life histories, few biographies of scientists make use of insights derived from psychology, another discipline that studies people, their thoughts, and their actions. This essay argues that recent theoretical work in psychology and tools developed for clinical psychological practice can help biographical historians of science create and present fuller portraits of their subjects' characters and temperaments and more nuanced analyses of how these traits helped shape their subjects' scientific work. To illustrate this thesis, the essay examines the early career of James McKeen Cattell--an influential late nineteenth- and early twentieth-century experimental psychologist--through a lens offered by psychology and argues that Cattell's actual laboratory practices derived from an "accommodation" to a long-standing "cognitive deficit." These practices in turn enabled Cattell to achieve more precise experimental results than could any of his contemporaries; and their students readily adopted them, along with their behavioral implications. The essay concludes that, in some ways, American psychology's early twentieth-century move toward a behavioral understanding of psychological phenomena can be traced to Cattell's personal cognitive deficit. It closes by reviewing several "remaining general questions" that this thesis suggests.

Gendered contexts: masculinity, knowledge, and attitudes toward biotechnology

Research into the public understanding of science has revealed that the effect of scientific knowledge on attitudes toward science is contextualized by gender; however there has not yet been an account of how gender contextualizes knowledge. This paper investigates how gender identification affects attitudes toward science, and tempers the effects of scientific knowledge on attitudes toward science. Utilizing data from the Eurobarometer 52.1, it is predicted that when males perceive a threat to their masculinity (as measured by a perceived threat to their financial security) they will become more likely to be aversive to biotechnology, and that increased levels of perceived threat will reduce the effects of knowledge on attitudes toward biotechnology. Moreover, it is predicted that these effects will be smaller than their female counterparts. All predictions are affirmed.     

Economic Analysis of Telecommunications: Theory and Applications edited by L. Courville,A. de Fontenay,R. Dobell (North Holland,Amsterdam, 1983) ISBN: 0-444-86674-4

The introduction of new technology has been of concern to banking unions but the chances of them effectively influencing such decisions are determined by the importance attached to the issue by members and their willingness to undertake industrial action. This paper reports a study which attempted to examine this issue by investigating union members’ experiences with various types of new technology, their attitudes towards those technologies and various aspects of their work lives and also their willingness to undertake industrial action over the introduction of new technology into their workplace.

Agency,sociomateriality, and configuration work

Social informatics research offers insights into the relationship between information technologies and social contexts. However, the material roles of information technologies, and their interplay with the agentic work of social actors, have not been addressed. Drawing on a field study of 37 mobile knowledge workers, we examine the dual material roles (enabling and constraining) played by information technologies in their work practices. We also investigate how these workers exert agency by fashioning multiple information technologies into a functioning digital assemblage. Although information technologies provide consequential affordances that enable mobilization of work across spaces and times, they simultaneously present design-driven, local, organizational, and temporal technological constraints that require mobile knowledge workers to engage in “configuration work” to make information technologies function effectively. Building on a sociomaterial perspective, we further discuss the interplay of information technologies and work practices enacted by mobile knowledge workers, in which both human and technological agency are materialized.     

Passing the torch of knowledge: Star death,collaborative ties,and knowledge creation

Stars hold a large portion of organizational knowledge, and their sudden absence may have non-trivial consequences for firms. In this study, I investigate what happens to the knowledge of star inventors following their absence. In particular, I consider the composition of stars' ties with coinventors and examine how it affects the future use of stars' knowledge (i.e., patents). Using the death of star inventors as an exogenous cause for their absence in firms, I find that the use of a star's patents in a firm's subsequent inventive efforts declines following the star's death. The results also indicate that when star inventors frequently collaborate with coinventors, the negative effect of stars' absence on the future use of their knowledge is somewhat alleviated. Further, the presence of central inventors in stars' collaboration networks increases the relative use of stars' knowledge in future inventions. The findings inform managers about conditions that favor “passing the torch” of knowledge from stars to their peers.     

Science, the South Pole, and the Japanese expedition of 1910-1912

In November 1910, Shirase Nobu (1861-1946) sailed from Tokyo Bay aboard the Kainan Maru as part of an international race for the South Pole. The Japanese had no history of polar exploration and looked to British precedence to compensate for their lack of experience. Following the British example required that they include a scientific dimension to their venture. It is clear, however, that Shirase and his men had little scientific understanding. Nevertheless, on failing to reach the Pole, science became the central aim of the expedition and the primary means to declaring their efforts a success.     

Instagram user characteristics and the color of their photos: Colorfulness,color diversity,and color harmony

This study aims to explore the relationships between Instagram user characteristics and color features of their photos. Based on the assumption that individuals who are similar in characteristics would exhibit a similar style in their social media photos, this study pays attention to color as one of the key elements of style. An online survey to 179 university students measured their Big Five personality traits, narcissism, life satisfaction, loneliness, attitude to Instagram, and gender, and their Instagram photos were analyzed in terms of colorfulness, color diversity, and color harmony. Total 25,394 photos were analyzed. Results suggest that (1) agreeableness was the most relevant user variable associated with all color features; (2) the color features of Instagram photos were different by gender; (3) neuroticism of Instagram users was negatively associated with the color harmony of their photos; (4) color diversity was negatively correlated with loneliness, and romantic loneliness in particular; (5) users’ attitude to Instagram and the color harmony of their photos were positively correlated; and (6) extraversion of Instagram users was positively correlated with the color diversity while openness was negatively correlated with the color diversity and color harmony of their photos. They reveal that the color features of Instagram photos are linked to the characteristics of their uploader. The present study contributes to the body of research on color preference and online self-presentation. It not only exemplifies how the stylometric approach can be adopted to SNS research but also presents the link between user characteristics and the features of their posts at pixel-level, including color.     

The Victorian Information Society: Surveillance, Bureaucracy, and Public Librarianship in 19th-Century Britain

Contrary to the "retro" image often awarded them, and despite their continuing enthusiasm and responsibility for the organization of printed materials, librarians are upbeat about the prospects of an information society driven primarily by electronic technologies, but in which libraries can play an important part. Public librarians detect a natural correlation between the historic democratic mission of their institution and the increased accessibility made possible by digitalized sources. The library community's acceptance of the information society idea as a "given" social phenomenon supports discourses that play down historical continuities and herald the dawn of a new age. Such discourses ignore or reject historical evidence that points to the existence of past information societies, revolutions, and infrastructures defined, in part, by the operation of indirect surveillance, constituted by the bureaucratic information systems of modernity. Victorian Britain serves as a good example of an early information society, to which public libraries, themselves micro-information societies, contributed significantly. The role played by public librarians in the Victorian information society, illustrated in this article by evidence drawn from the contemporary library press, is seen in their preoccupation with the surveillance and ordering of knowledge; their adoption for library operations of the businesslike, bureaucratic procedures described recently by business historians; and their panoptic tracking of users and their activities.     

Technological innovation capabilities in the thin film transistor-liquid crystal display industries of Japan, Korea, and Taiwan

The study described herein uses US Patent and Trademark Office data to assess variations in technological innovation capabilities, and their influence on market performance, among leading TFT-LCD producers in Japan, Korea, and Taiwan. The empirical results suggest that TFT-LCD producers in Korea and Taiwan built innovation capabilities by creating complementary knowledge for Japanese firms, whose technologies lead the way in the industry. The results also show that latecomers sought to expand production by selecting certain technological fields, but that they exploited these fields in different ways. Specifically, Korean conglomerates increased their scale of technology in order to improve their technological positions, while Taiwanese producers pursued innovations that strengthened their technological efficiency. While Japanese firms led the way in terms of both technology and market share during the 1990s, they then evolved to become merely technological leaders from 2000 onwards. However, Japanese firms have since renewed their business strategies to counter the aggressive market expansion of their competitors by strengthening the protection of their intellectual property rights through inter-keiretsu collaborations in technological niches, and by securing leadership in the market in high value-added key components in order to retain more of the profits from their own innovations. Four policy imperatives for both technology leading and latecomer countries regarding the development of sustainable industries associated with the industrial cycle and market dynamics are discussed.     

CIDER: Concept-based image diversification,exploration, and retrieval

Many of the approaches to image retrieval on the Web have their basis in text retrieval. However, when searchers are asked to describe their image needs, the resulting query is often short and potentially ambiguous. The solution we propose is to perform automatic query expansion using Wikipedia as the source knowledge base, resulting in a diversification of the search results. The outcome is a broad range of images that represent the various possible interpretations of the query. In order to assist the searcher in finding images that match their specific intentions for the query, we have developed an image organization method that uses both the conceptual information associated with each image, and the visual features extracted from the images. This, coupled with a hierarchical organization of the concepts, provides an interactive interface that takes advantage of the searchers’ abilities to recognize relevant concepts, filter and focus the search results based on these concepts, and visually identify relevant images while navigating within the image space. In this paper, we outline the key features of our image retrieval system (CIDER), and present the results of a preliminary user evaluation. The results of this study illustrate the potential benefits that CIDER can provide for searchers conducting image retrieval tasks.

Users’ evaluation of digital libraries (DLs): Their uses,their criteria,and their assessment

Millions of dollars have been invested into the development of digital libraries. There are many unanswered questions regarding their evaluation, in particular, from users’ perspectives. This study intends to investigate users’ use, their criteria and their evaluation of the two selected digital libraries. Nineteen subjects were recruited to participate in the study. They were instructed to keep a diary for their use of the two digital libraries, rate the importance of digital library evaluation criteria, and evaluate the two digital libraries by applying their perceived important criteria. The results show patterns of users’ use of digital libraries, their perceived important evaluation criteria, and the positive and negative aspects of digital libraries. Finally, the relationships between perceived importance of digital library evaluation criteria and actual evaluation of digital libraries and the relationships between use of digital libraries and evaluation of digital libraries as well as users’ preference, experience and knowledge structure on digital library evaluation are further discussed.     

Imperialism, colonial identity, and race in Algeria, 1830-1870. The role of the French Medical Corps

During the military administration of Algeria, which lasted for forty years, the foundation of the French colony was laid. Indispensable to the military in Algeria was its sizable medical corps. While the ostensible reason for its presence was to maintain the soldiers' health and thus the army's efficiency, it role extended beyond this primary objective. Starting from the intellectual and political influences that shaped the training in France of the members of the medical corps, this essay examines the ways in which they contributed to the creation of a French colonial space in Algeria. It traces how their involvement in the intellectual, cultural, and political life of the colony enabled them both to further their own ambitions and to influence wider developments. It explores how colonial physicians and surgeons, deemed to be among the most efficient agents of the civilizing mission owing to their humane contacts with the indigenous population, in fact contributed to that population's categorization and marginalization.     

Murdered bread, living bread: Doris Grant and the homemade, wholemeal loaf

Doris Grant (1905-2003), a middle-class, British housewife, published numerous books from the 1940s into the 1970s urging her fellow housewives to bake organic, wholemeal bread for their families. This article argues that Grant's arguments defy easy categorization as either 'conservative' or 'progressive'. On the one hand, her targeted appeal to women reflected a traditional, conservative understanding of gender roles: women were, first and foremost, wives and mothers and therefore naturally responsible for family diet and health. On the other hand, Grant also pushed her readers to look beyond their homes and recognize a dangerous food supply system that was impinging on their daily lives. She demanded that her readers reject comfortable complicity in this system and preached the value of individual action in effecting substantive change.     

2008 Benjamin Franklin medal in life science is Presented to Victor Ambros, Ph.D. (University of Massachusetts Medical School, Worcester, Massachusetts), Gary Ruvkun, Ph.D. (Harvard Medical School, Massachusetts General Hospital, Boston, Massachusetts) and David Baulcombe, Ph.D., FRS (University of Cambridge, Cambridge, UK)

The discovery of small RNAs that can turn off genes has given us a new way to think about how genes are regulated. These molecules are present in all complex organisms and are thought to regulate upwards of 30% of human genes. Due to their small size, their discovery was surprisingly recent and was underappreciated initially. Beginning with two back-to-back papers published in 1993, the labs of Victor Ambros and Gary Ruvkun reported the first small RNA (now known as a microRNA or miRNA) and how it regulated a target mRNA in the roundworm Caenorhabditis elegans through base-pairing interactions. It took until 1999 for another report to document novel small RNAs in complex systems, when David Balcoumbe discovered similarly sized molecules, now known as small interfering RNAs or siRNAs, that were associated with shutting off or “silencing” genes in plants. A frenzy of reports on small RNAs and their roles in turning off genes ensued with many researchers including Ambros, Ruvkun, and Baulcombe prominently participating. Almost instantly it became clear that small RNAs were not a quaint oddity exclusive to the worm, and molecular biology was never the same. Now we know that these molecules are critical for normal growth and development, are associated with cancer and other diseases, and have tremendous applied potential to improve agriculture and human health.
