History and scientific practice in the construction of an adequate philosophy of science: revisiting a Whewell/Mill debate

William Whewell raised a series of objections concerning John Stuart Mill’s philosophy of science which suggested that Mill’s views were not properly informed by the history of science or by adequate reflection on scientific practices. The aim of this paper is to revisit and evaluate this incisive Whewellian criticism of Mill’s views by assessing Mill’s account of Michael Faraday’s discovery of electrical induction. The historical evidence demonstrates that Mill’s reconstruction is an inadequate reconstruction of this historical episode and the scientific practices Faraday employed. But a study of Faraday’s research also raises some questions about Whewell’s characterization of this discovery. Thus, this example provides an opportunity to reconsider the debate between Whewell and Mill concerning the role of the sciences in the development of an adequate philosophy of scientific methodology.Keywords: Inductivism; Experiment; Theory; Methodology; Electromagnetism

The municipal archives of the City of New York

Ith some 100,000 cubic feet of civic documents, vital and building records, libers, films and photographs, New York City's Municipal Archives is a magnet for researchers. Among those who benefit from centralized access to the wealth of material deposited in the Archives by city government agencies are genealogists, urban scholars and architectural historians

Discovery of SN 2009nz Associated with GRB 091127

We report SMARTS, Gemini and Swift-UVOT observations of the optical transient (OT) associated with gamma-ray burst (GRB) 091127, at redshift 0.49, taken between 0.9 hr and 102 days following the Swift trigger. In our early-time observations, the OT fades in a manner consistent with previously observed GRB afterglows. However, after 9 days post-burst, the OT is observed to brighten for a period of ~2 weeks, after which the source resumes fading. A comparison of this late-time "bump" to SN 1998bw (the broad-lined Type Ic supernova associated with GRB 980425), and several other GRB supernovae (SNe), indicates that the most straightforward explanation is that GRB 091127 was accompanied by a contemporaneous SN (SN 2009nz) that peaked at a magnitude of M_V=-19.0+/-0.2. SN 2009nz is globally similar to other GRB supernovae, but evolves slightly faster than SN 1998bw and reaches a slightly dimmer peak magnitude. We also analyze the early-time UV-optical-IR spectral energy distribution of the afterglow of GRB 091127 and find that there is little to no reddening in the host galaxy along the line-of-slight to this burst.Comment: minor edits, accepted by ApJ Letter

Forecasting Chilean Inflation From Disaggregate Components

In this paper an exercise is performed to determine the usefulness of utilizing disaggregated price data to forecast headline inflation more accurately. A number of methods based on univariate and multivariate autoregressive models are used for different levels of disaggregation for a period of stable inflation and a period of accelerating inflation. The results show that a certain level of disaggregation could be beneficial when inflation is not low and stable, suggesting that under certain circumstances the disaggregate approach captures the underlying dynamics of inflation more efficiently. The benefits are noticeable for the three-, six- and twelve-month horizons, as opposed to the one-month horizon, where improvements seem negligible.

Leaving Home: What Economics Has to Say about the Living Arrangements of Young Australians

Like their counterparts elsewhere, more young Australians than ever are delaying the move to establish residential independence from their parents. This paper reviews the developing economics literature surrounding young people’s decisions to continue living in their parents’ homes in order to begin to assess the causes and consequences of this decision. In particular, co-residence with parents appears to be an important form of intergenerational support for young adults. It is important to understand the extent to which young people rely on this form of support as they complete their education, enter the labour market, and establish themselves as independent adults. Specific attention is paid to the ways in which Australian income-support, education, and housing policies may influence these patterns.household decision-making, economics of the family

Using an Online Sample to Estimate the Size of an Offline Population.

Online data sources offer tremendous promise to demography and other social sciences, but researchers worry that the group of people who are represented in online data sets can be different from the general population. We show that by sampling and anonymously interviewing people who are online, researchers can learn about both people who are online and people who are offline. Our approach is based on the insight that people everywhere are connected through in-person social networks, such as kin, friendship, and contact networks. We illustrate how this insight can be used to derive an estimator for tracking the digital divide in access to the Internet, an increasingly important dimension of population inequality in the modern world. We conducted a large-scale empirical test of our approach, using an online sample to estimate Internet adoption in five countries (n ≈ 15,000). Our test embedded a randomized experiment whose results can help design future studies. Our approach could be adapted to many other settings, offering one way to overcome some of the major challenges facing demographers in the information age

Do Selection Criteria Make a Difference? Visa Category and the Labour Force Status of Australian Immigrants.

This paper assesses the role of selection criteria in the immigrant settlement process by analysing the labour force status of immigrants entering Australia under different immigration programs. In particular, do immigrants selected on the basis of labour market skills rather than family relationships have higher participation and employment rates immediately after migration? To what extent does this represent a head start as opposed to long-term labour market advantage? Information fron the Longitudinal Survey of Immigrants to Australia (LSIA) are used address these questions.IMMIGRATION ; LABOUR MARKET ; AUSTRALIA
