Book Review: Introducing Monte Carlo Methods with R

In this article we propose a nonparametric test for poolability in large dimensional semiparametric panel data models with cross-section dependence based on the sieve estimation technique. To construct the test statistic, we only need to estimate the model under the alternative. We establish the asymptotic normal distributions of our test statistic under the null hypothesis of poolability and a sequence of local alternatives, and prove the consistency of our test. We also suggest a bootstrap method as an alternative way to obtain the critical values. A small set of Monte Carlo simulations indicate the test performs reasonably well in finite samples.     

Temporal blindspots in Occupy Philadelphia

ABSTRACT

This paper analyzes the disjunctive temporalities of Occupy Philadelphia’s political constituencies. Drawing on both an ethnographic participant observation study of the Occupy Philadelphia movement and Philadelphia’s neoanarchist political communities, and on recent social scientific theorization of events, the paper argues that contradictory ideas about temporal timescales, momentum, duration, sequences, and rhythms of tactical and strategic action problematized interaction and coordination among movement participants. These points of coordinative disjuncture can be traced back to differences in participants’ ideas about prefigurative politics and strategic temporalities. Limning the temporal expectations and experiences of social movement participants, this paper contributes to the examination of both linkages and disjunctures between eventful temporalities experienced in moments of protest and in social movements with diverse timescales.     

Action as Will-Power

The concept of power, as commonly formulated in contemporary sociology, is noted to lack any reference to the critical dimension of personal conative striving, or will-power. This deficiency is shown to stem from an overly cognitive conception of action, one in which acts are seen to embody choice and meaning but not emotion or effort, a view that has been reinforced by the use of trivial, easily-accomplished acts as examples to illustrate the nature of action. A perspective is advocated that redresses this imbalance; one that accepts that the immediate cause of all true actions is an act of will and that action is best conceived of as behaviour that individuals allow to happen to them. Power is then defined as an individual's ability to initiate and maintain action despite behavioural resistance, a conceptualization that closely links it to the concept of 'character'. This perspective on human conduct is then shown to be identical to that adopted by Weber in The Protestant Ethic and the Spirit of Capitalism .     

Aids and Bereavement

People bereaved by AIDS are likely to be in special need of support by reason of the social situations that accompany this type of loss and the risk of infection in the survivors. Problems associated with grief, depression, and the misuse of medicinal and other drugs are common. Special problems arise when the bereaved are partners, spouses, or parents of the deceased. Issues requiring special attention include emotional overload in both clients and counselors, judgmental attitudes, secrecy, anger, guilt, and the vicious circles that easily arise and can perpetuate problems.     

Disability,politics and poverty in a majority world context

This paper argues that the spread of free market economics throughout the world has generated unprecedented inequalities within and between nation states. This has led to the systematic exclusion of people with perceived impairments from the mainstream of economic and community life in almost all societies, the generation of an international disabled people’s movement, and their demand for legal frameworks with which to address the multiple deprivations encountered by people viewed as ‘disabled’. It is argued that the poverty and exclusion encountered by disabled people and other oppressed groups in all societies will not be eliminated without fundamental structural change at the international level.     

An autecological interpretation of the firm and its environment

Explaining the survival and failure of firms is an important issue for researchers and managers of firms in society. Ecological approaches to the study of firms have existed for over 100 years, and have been increasingly popular during the past 40 years, especially since the pioneering works of Hannan and Freeman on one hand, and Aldrich on the other. This paper, in keeping with recent developments elsewhere in mainstream ecology outlines and positions the theoretical and philosophical foundations of an alternative ecological approach, autecology, that has not yet been formulated for the study of firms. The autecological approach affords the individual firm more autonomy in creating its own future evolutionary trajectory. The idea of an ecological complex is developed to provide clear focus on what is central to the application of autecology to the study of firms. The paper also considers several emergent research opportunities that highlight the potential value of employing an autecological approach to the study of firms.     

Calculating the total vote where the district magnitude is greater than one: A test of some algorithms using British local election data

Electoral analysis using aggregate data relies on the availability of accurate voting statistics. One vital piece of information, often missing from official electoral returns, particularly British local government elections, is the total number of valid ballot papers. This figure is essential for the calculation of electoral turnout. When voters have a single vote and official information about the number of ballot papers issued is missing, a figure for the total vote can still be derived. However, local elections in Britain frequently use a system of multiple-member wards, where voters have as many votes as there are seats to be filled. In such cases, calculating the total vote and, hence, the turnout does present a real problem. It cannot be assumed that all voters will use their full quota of votes or that voters will cast a ballot in favour of a single party. This paper develops and tests diff erent algorithms for calculating the total vote in such circumstances. We conclude that the accuracy of an algorithm is closely related to the structure of party competition. The findings of this paper have a number of important implications. First, the difficulties in calculating the turnout in multiple-member wards are identified. This will inform the debate about public participation in the local electoral process. Second, the method for deriving a figure for the total vote has an important bearing on a number of other statistics widely employed in electoral analysis.     

Detection of multiple undocumented change-points using adaptive Lasso

The problem of detecting multiple undocumented change-points in a historical temperature sequence with simple linear trend is formulated by a linear model. We apply adaptive least absolute shrinkage and selection operator (Lasso) to estimate the number and locations of change-points. Model selection criteria are used to choose the Lasso smoothing parameter. As adaptive Lasso may overestimate the number of change-points, we perform post-selection on change-points detected by adaptive Lasso using multivariate t simultaneous confidence intervals. Our method is demonstrated on the annual temperature data (year: 1902–2000) from Tuscaloosa, Alabama.
