Who Protests in America: An Analysis of Three Political Alternatives—Inaction,Institutionalized Politics,or Protest

Theories of social movements and collective action typically present social protest as one of three alternatives available to the individual: inaction, institutionalized political action, or protest. These political alternatives are rarely considered simultaneously nor are they modeled explicitly. In this paper we make use of survey data from a representative sample of the United States population. We employ multinomial logistic regression to determine what differentiates those who protest from those who engage only in institutionalized politics and from those who engage in no political action. We find that those who engage in social protest are similar in many respects to those who engage actively in institutionalized politics, yet education on social and political issues, participation in community organizations, and frequent church attendance increases the likelihood that individuals will engage in protest relative to institutionalized politics.     

Neighbourhood and preventive strategies with children and families: what works?

This paper argues that the 1989 Children Act has provided a poor context for discussing ‘prevention’. The Act has not helped the development of either a proper understanding of childhood disadvantages or policies to deal with it. This paper presents a fresh perspective on ‘prevention’ in the context of Government initiatives such as Sure Start, and argues for analysis of neighbourhood disadvantages and neighbourhood-based policies. The ‘geography of disadvantage’ has to be understood as well as the facts of disadvantage, that is, the concentrations and persistence of variations in income, health, and educational outcomes as they affect children. Examples of early years programmes and projects are reviewed for their impact on disadvantaged children and their families. Copyright © 1999 John Wiley & Sons, Ltd.     

Globalization, the structure of the world economy and economic development

How does the structure of the world economy determine the gains from participation therein? In order to answer this question, we conduct a state of the art network analysis of international trade to map the structure of the international division of labor (IDL). We regress cross-national variation in economic growth on positional variation and mobility of countries within the IDL from 1965 to 2000. We find that the highest rates of economic growth occurred to countries in the middle of the IDL over the course of globalization. Second, we find that upper tier positions in the IDL are converging with each other, but diverging from the lower tier. This suggests that the mechanism underlying the rapid economic growth in intermediate positions was their uniquely high rates of upward mobility, in turn a function of their middling position. Taken together, these findings suggest that a country’s long-term economic development is conditioned by its position in the IDL.     

Risk of Legionellosis in residential areas around farms irrigating with municipal wastewater

The conservation of freshwater is of both global and national importance, and in the United States, agriculture is one of the largest consumers of this resource. Reduction of the strain farming puts on local surface or groundwater is vital for ensuring resilience in the face of climate change, and one possible option is to irrigate with a combination of freshwater and reclaimed water from municipal wastewater treatment facilities. However, this wastewater can contain pathogens that are harmful to human health, such as Legionella pneumophila, which is a bacterium that can survive aerosolization and airborne transportation and cause severe pneumonia when inhaled. To assess an individual adult's risk of infection with L. pneumophila from a single exposure to agricultural spray irrigation, a quantitative microbial risk assessment was conducted for a scenario of spray irrigation in central Illinois, for the growing seasons in 2017, 2018, and 2019. The assessment found that the mean risk of infection for a single exposure exceeded the safety threshold of 10^–6 infections/exposure up to 1 km from a low-pressure irrigator and up to 2 km from a high-pressure irrigator, although no median risk exceeded the threshold for any distance or irrigator pressure. These findings suggest that spray irrigation with treated municipal wastewater could be a viable option for reducing freshwater consumption in Midwest farming, as long as irrigation on windy days is avoided and close proximity to the active irrigator is limited.     

Web based resource for Statistical Consultants in the Pharmaceutical Industry

The intention of this article is to highlight sources of web-based reference material and software that will aid consulting statisticians when designing clinical trials. The article includes websites that provide links to explanation of statistical concepts for non-statisticians, regulatory guidelines, and free statistical study design software.     

Eighth‐Grade School Form and Resilience in the Transition to High School: A Comparison of Middle Schools and K‐8 Schools

We examine a set of academic and social outcomes in 9th grade, comparing middle school attendees with those who attended K‐8 schools. Previous research with these data has shown that there are few differences in 8th‐grade outcomes by school type. Here we extend these findings to determine whether school form influences student outcomes in the first year of high school. The results reveal several domains in which attendance at a middle school results in worse outcomes (e.g., greater rates of course failure); however, we find that a large portion of the difference by type of a student's 8th‐grade school is accounted for by differential rates of attendance at the district's magnet schools. That is, our results indicate that type of school attended during the middle grades is significantly and positively related to magnet school attendance and thereby on the academic outcomes in the 9th‐grade year.     

A weighted test of internal symmetry

This study examines extensions of McNemar's Test with multinomial responses, and proposes a linear weighting scheme, based on the distance of the response change, that is applied to one of these extensions (Bowker's test). This weighted version of Bowker's test is then appropriate for ordinal response variables. A Monte Carlo simulation was conducted to examine the Type I error rate of the weighted Bowker's test for a cross-classification table based on a five-category ordinal response scale. The weighted Bowker's test was also applied to a data set involving change in student attitudes towards mathematics. The results of the weighted Bowker's test were compared with the results of Bowker's test applied to the same set of data.
