Originally published in 1980, this book examines the major issues in the philosophy of social science, paying specific attention to cross-cultural understanding, humanism versus scientism, individualism versus collectivism, and the shaping of theory by evaluative commitment. Arguing for a cross-cultural conception of human beings, the authors defend humanism and individualism, and reject the notion that social inquiry is necessarily vitiated by an adherence to values

The most comprehensive discussion available of the work of philosopher, John McDowell. Contains newly commissioned papers by distinguished philosophers on McDowell's work, along with substantial replies to each by McDowell himself. The contributors are philosophers with international reputations for their work in the areas in which they are contributing. Covers the whole of McDowell's philosophy, including his contributions in ancient philosophy, moral philosophy, philosophy of mind, philosophy of language, metaphysics and epistemology. McDowell's replies to the contributions in this volume co

Urban has developed an elastic and powerful approach to the analysis of massive datasets using Amazon Web Services' Elastic MapReduce (EMR) and the Spark framework for distributed memory and processing. The goal of the project is to deliver powerful and elastic Spark clusters to researchers and data analysts with as little setup time and effort possible, and at low cost. To do that, at the Urban Institute, we use two critical components: (1) an Amazon Web Services (AWS) CloudFormation script to launch AWS Elastic MapReduce (EMR) clusters (2) a bootstrap script that runs on the Master node of the new cluster to install statistical programs and development environments (RStudio and Jupyter Notebooks). The Urban Institute's Spark for Social Science Github page holds code used to setup the cluster and tutorials for learning how to program in R and Python.

Many studies have examined the role of mean climate change in agriculture, but an understanding of the influence of inter-annual climate variations on crop yields in different regions remains elusive. We use detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide. While some areas show no significant influence of climate variability, in substantial areas of the global breadbaskets, >60% of the yield variability can be explained by climate variability. Globally, climate variability accounts for roughly a third (~32–39%) of the observed yield variability. Our study uniquely illustrates spatial patterns in the relationship between climate variability and crop yield variability, highlighting where variations in temperature, precipitation or their interaction explain yield variability. We discuss key drivers for the observed variations to target further research and policy interventions geared towards buffering future crop production from climate variability.

We generate the first cross-city panel dataset of land-use reforms that increase or decrease allowed housing density and estimate their association with changes in housing supply and rents. To generate reform data, we use machine-learning algorithms to search US newspaper articles between 2000 and 2019, then manually code them to increase accuracy. We merge these data with US Postal Service information on per-city counts of addresses and Census data on demographics, rents, and units affordable to households of different incomes. We then estimate a fixed-effects model with city specific time trends to examine the relationships between land-use reforms and the supply and price of rental housing. We find that reforms that loosen restrictions are associated with a statistically significant 0.8% increase in housing supply within three to nine years of reform passage, accounting for new and existing stock. This increase occurs predominantly for units at the higher end of the rent price distribution; we find no statistically significant evidence that additional lower-cost units became available or moderated in cost in the years following reforms. However, impacts are positive across the affordability spectrum and we cannot rule out that impacts are equivalent across different income segments. Conversely, reforms that increase land-use restrictions and lower allowed densities are associated with increased median rents and a reduction in units affordable to middle-income renters.

Purpose
This paper reflects on the Sustainability Research Symposium (SRS), a long-term student-led initiative (seven years) at McGill University in Montréal, Canada, that seeks to foster interdisciplinary dialogue among students and researchers by using the sustainability sciences as a bridge concept. The purpose of this study is to explore the effectiveness of the SRS in fostering sustainability literacy.


Design/methodology/approach
Past participants of the SRS were invited to complete a survey to gauge the strengths and weaknesses of the symposia from a participants' perspective. A mix of descriptive statistics and axial and thematic coding were used to analyze survey responses (n = 56). This study links theory and practice to explore the outcomes of symposia as tools for students to engage with sustainability research in university campuses.


Findings
Survey findings indicated that participants are from multiple disciplinary backgrounds and that they are often interested in sustainability research without being identified as sustainability researchers. Overall, the survey findings suggested that student-organized symposia can be effective mechanisms to enhance exposure to interdisciplinary research and to integrate sustainability sciences outside the classroom.


Practical implications
Despite being a one-day event, the survey findings suggest that symposia can offer an "initiation" toward interdisciplinary dialogue and around sustainability research that can have lasting impacts beyond the time frame of the event.


Originality/value
Although research symposia are widespread in university campuses, there is little published information on the effectiveness of student-organized symposia as vectors for sustainability literacy. This original contribution presents a case study of the effectiveness of an annual symposium at one Canadian university, organized by students from the Faculties of Science, Arts and Management.

Achieving sustainable global food security is one of humanity's contemporary challenges. Here we present an analysis identifying key "global leverage points" that offer the best opportunities to improve both global food security and environmental sustainability. We find that a relatively small set of places and actions could provide enough new calories to meet the basic needs for more than 3 billion people, address many environmental impacts with global consequences, and focus food waste reduction on the commodities with the greatest impact on food security. These leverage points in the global food system can help guide how nongovernmental organizations, foundations, governments, citizens' groups, and businesses prioritize actions.
