Climate and marriage in the Netherlands, 1871–1937

Environmental factors such as climate variability can place significant constraints on demographic behavior in a range of settings. However, few studies investigate the relationships between demography and climate in historical contexts. Using longitudinal individual-level demographic data from the Historical Sample of the Netherlands (HSN) and climate and economic data from 1871 to 1937, we examine the effects of climate variability on marriage. This analysis reveals that marriage increases with negative environmental conditions such as cold temperatures, riverine flooding, and high rye prices. These findings are not consistent with a Malthusian narrative of marriage behavior or with the expectation that environmental constraints were stronger in the historical past.     

Erratum to: Heterogeneous climate effects on human migration in Indonesia

We examine the effect of anomalous temperatures, rainfall levels, and monsoon timing on migration outcomes in Indonesia. Using panel data from the Indonesian Family Life Survey and high-resolution climate data, we assess whether intra- and inter-province moves are used as a response to climatic shocks. We evaluate the relative importance of temperature, rainfall, and monsoon timing for migration. Temperature and monsoon timing have significant effects, and these do not operate in the direction commonly assumed. Estimated effects vary according to individuals’ gender, membership in a farm household, and location. We also analyze climate effects on sources of household income, which point to the multi-phasic nature of household responses. Results undermine narratives of a uniform global migratory response to climate change and highlight the heterogeneous use of migration as a response to such changes. By extending previous research on environmentally induced migration in Indonesia, we also highlight the sensitivity of estimates to alternative climate and migration measures.     

Pupillary Responses to Static Images of Men and Women: A Possible Measure of Sexual Interest?

The pupil dilates to images that are arousing. In Experiment 1, we examined if the pupil’s response to brief presentations (2,000 ms) of static images could be used to identify individuals’ sexual orientation. Participants were grouped according to their self-reported gender and sexual orientation (male heterosexual, N = 20; male bisexual, N = 13; male homosexual, N = 19; female heterosexual, N = 28; female bisexual, N = 21; female homosexual, N = 17). Pupil size was monitored to images of men in seminude poses, women in seminude poses, or neutral images. Every group showed the same pattern of responses, with the greatest dilation to male images, then female images, and least dilation to the neutral images. Experiment 2 used more tightly controlled stimuli and tested at two different image durations (150 and 3,000 ms). Both heterosexual men (N = 18) and women (N = 20) showed greater pupil dilation to images of nude men than to nude women. However, in Experiment 3, where we reduced the erotic content by using images of clothed models, both heterosexual men and women showed greater pupil dilation to images of women. The results showed that while the pupil does dilate strongly to sexual imagery, its response to these brief static images does not correspond to a person’s sexual orientation in a simple manner.     

“Do We Have A Customer?” — A Team Approach To Intake

This article examines some of the ambiguities surrounding requests for assistance in the voluntary sector. The authors have developed a team approach at the ‘intake’ stage for clients whose requests often demand a well-thought-out response in order, as Haley suggests we must, “to start well”. Some of the literature about ‘beginning with families’ is examined, and the complex issues of ‘engaging’ and ‘joining’ are discussed. It is suggested that not every ‘shopper’ is necessarily a ‘customer’ for our wares, but that they are almost certainly shopping for something. ‘Emergency’ and ‘crisis’ calls are distinguished, and different responses to each are indicated. Finally, the procedures used are described, within the context of this particular voluntary agency, so that readers may distinguish what could be applicable in different contexts.     

Strategies for engineered negligible senescence

This Perspective summarizes presentations at the 10th Congress of the International Association of Biomedical Gerontology, which was held in Cambridge, England in September 2003. The seminar topics ranged from telomeres to ethics, stem cells to limb regeneration. The meeting organizer, Aubrey de Grey, is a leading proponent of life extension through biological engineering.
