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.     

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.     

“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.     

Negotiating control and achieving performance in international joint ventures: A conceptual model

Adapting well-established organization theories to international joint ventures (IJVs), this paper develops an overarching theoretical model of the determinants and effects of parent control of IJVs from an interpartner bargaining power perspective. Drawing upon power dependence, transaction costs, and agency theories, we argue that the relative bargaining power between IJV partners serves as the key determinant of control structure, and that control exerts a direct effect on the venture's performance. In addition, government influence and interpartner working relationship are critical factors that complicate the linkage between control and performance but may help to explain past conflicting results. Propositions regarding these relationships are formed for future empirical test, and implications and directions for future research are provided.     

Out of Sight,Out of Mind? Geographic and Social Predictors of Flood Risk Awareness

The persistent gap in flood risk awareness in Canada, and elsewhere in North America, is a continual source of worry for researchers and emergency managers; many people living in at‐risk places are simply unaware of risks and of their proximity to hazards. This study seeks to understand which residents were aware of flood risk, using unique representative survey data of Calgary residents living in the city's flood‐prone neighborhoods collected after the devastating and costly 2013 Southern Alberta Flood. The article uses logistic regression models to analyze which residents were aware of risk to their homes. Findings indicate that, in addition to various demographic predictors, many of the geographic predictors (including the elevation of one's home relative to the river) are significant predictors of awareness. Having a direct sight line to one of Calgary's two rivers is also a significant predictor in some of the models, suggesting that the visibility of hazards matters for flood risk perception, although this effect fades when many of the geographic predictors are added. Finally, the models indicate that several variables related to local, neighborhood‐based social networks are significant as well. These findings reveal that both physical surroundings and social context are important for understanding risk awareness. The article concludes by discussing the relevance for social science research on disasters and hazards, as well as for planners and emergency managers.
