This paper contrasts the research strategies of two women reformers, Florence Kelley and Ellen Swallow Richards, which entailed different strategies of social reform. In the early 1890s, social activist Florence Kelley used the social survey as a weapon for legal reform of the working conditions of women and children in Chicago's sweatshop system. Kelley's case shows that her surveys were most effective as "grounded" knowledge, rooted in a local community with which she was well acquainted. Her social survey, re-enacted by lawmakers and the press, provided the evidence that moved her target audience to legal action. Chemist and propagator of the Home Economics Movement Ellen Richards situated the social problem, and hence its solution, not in exploitative working conditions, but in the inefficient and wasteful usage of available resources by the poor. Laboratory work, she argued, would enable the development of optimal standards, and educational programs should bring these standards to the household by means of models and exhibits. With this aim, she constructed public spaces that she ran as food laboratories and sanitary experiments. Kelley and Richards thus crossed the doorsteps of the household in very different ways. While Florence Kelley entered the household to change the living and working conditions of the poor by changing the law, Richards flipped the household inside out by bringing women into hybrid public laboratory spaces to change their behavior by experiment and instruction.

In this comparative historical analysis, we will analyze the intellectual tendency that emerged between 1946 and 1956 to take advantage of the popularity of communication theory to develop a kind of informational epistemology of statistical mechanics. We will argue that this tendency results from a historical confluence in the early 1950s of certain theoretical claims of the so-called English School of Information Theory, championed by authors such as Gabor (1956) or MacKay (), and from the attempt to extend the profound success of Shannon's ([1948] 1993) technical theory of sign transmission to the field of statistical thermal physics. As a paradigmatic example of this tendency, we will evaluate the intellectual work of Léon Brillouin (), who, in the mid-fifties, developed an information theoretical approach to statistical mechanical physics based on a concept of information linked to the knowledge of the observer.

This paper explores how the Belgian mathematician Paul Mansion became interested in probability theory. In comparison to many other countries at the time, probability theory had a much stronger presence in Belgium. In addition, Mansion, who was an avowed Catholic militant, had found probability theory to be a useful means of reflecting on certain problems pertaining to determinism and randomness that were arising in scientific debates at the time. Mansion's work took place during a time of consolidation of mathematical education in Belgium, as well as a new interest in probabilistic results and the foundation of the Institute for Philosophy in Louvain by his friend Désiré Mercier. The present paper addresses how these aspects intersected at the turn of the twentieth century.

This study contributes to the discussion on the development of eugenics in Central-Eastern Europe by tracing the way that eugenic ideas entered into medical decision-making in Hungary. Through a case study that reviews the professional argumentation of the gynecological management of tuberculosis pregnancies, this paper shows that the subordination of individual reproductive rights to state interests was influenced by the ideas of eugenics, which had begun to enter into the professional public health discourse. A eugenically informed morality was envisioned, to guide decision-making in the interest of the Hungarian "race." This biopolitically important morality can be viewed as an early influence on the formulation of biological citizenship. Leading figures were divided on how to ensure such morality: some scholars argued that education is the key, others thought that the state, and state actors, should act radically in the interest of the population and decide on behalf of the individual. Radical methods, such as the termination of pregnancies and sterilization of women, were among the practices of gynecologists. Although abortion and sterilization were not widespread and never became official therapeutic solutions for tuberculosis pregnancies, they were nonetheless part of a discourse that preceded the eugenic institutions of the interwar years.

Agent-based social simulations have historically been evaluated using two criteria: verification and validation. This article questions the adequacy of this dual evaluation scheme. It claims that the scheme does not conform to everyday practices of evaluation, and has, over time, fostered a theory-practice gap in the assessment of social simulations. This gap originates because the dual evaluation scheme, inherited from computer science and software engineering, on one hand, overemphasizes the technical and formal aspects of the implementation process and, on the other hand, misrepresents the connection between the conceptual and the computational model. The mismatch between evaluation theory and practice, it is suggested, might be overcome if practitioners of agent-based social simulation adopt a single criterion evaluation scheme in which: i) the technical/formal issues of the implementation process are tackled as a matter of debugging or instrument calibration, and ii) the epistemological issues surrounding the connection between conceptual and computational models are addressed as a matter of validation.

During the first half of the 1970s, climate research gained a new significance and began to be perceived within political and academic circles as being worthy of public support. Conventional explanations for this increased status include a series of climate anomalies that generated awareness and heightened concern over the potentially devastating effects of climate change. Controversial climatologist Reid Bryson was one of the first to publicly promote what he saw as a definitive link between these climate anomalies and unidirectional climate change in the fall of 1973, and rising food prices in the same year gave him a platform on which to air his views to receptive senior members of the US Congress. Bryson's testimony before a US Senate subcommittee offers a unique glimpse into how he was able to successfully resonate his agenda with that of senior politicians in a time of crisis, as well as the immediate responses of those senior US politicians upon first hearing climate change arguments. Bryson was one of the most prominent US climatologists to break a taboo against making bold climatological predictions and de-facto policy recommendations in public. As a result, although Bryson was criticized by many in the climatological community, his actions instigated the involvement of other scientists in the public arena, leading to an important elevation in US public climate discourse.
