The Cost of Majority‐Party Bias: Amending Activity under Structured Rules

All major legislation in the House necessitates a special rule from the Rules Committee before it can be brought to the chamber floor. These rules often strictly limit floor amendments to bills considered by the House. Scholars of political parties have argued that the House majority party can bias policy output away from the floor median through its usage of restrictive rules. In this article, we argue that in order to secure the passage of restrictive rules, the majority often makes concessions to centrist legislators through the amending process. We examine this theory using a newly collected data set that includes all amendments considered by the Rules Committee during the construction of structured rules in the 109th, 110th, and 111th Congresses (2005–2010). Our results are mixed, but they do suggest that moderate members of the majority party often receive concessions via amendments for their support of the majority party's agenda‐setting regime.     

Dental Age Estimation: A Test of the Reliability of Correctly Identifying a Subject Over 18 Years of Age Using the Gold Standard of Chronological Age as the Comparator

This study was designed to test the reliability of using the third molars to demarcate between child and adult status. A total of 2000 dental panoramic tomographs were used for assessment of the calculated age using the 8‐stage system of tooth development and applied to all four third molars. The LL8 was also assessed using this 8‐stage system. For each tooth development stage, the Normal distribution and percentile summary data were estimated. The calculated dental age compared with the chronological age was statistically significantly different (p < 0.001) for both females and males giving underestimates of the true age. Comparison of single tooth dental age and chronological age was only slightly different. The most important finding is that the assignment to above or below the 18‐year threshold, in the age range 17 years to 19 years, could be wrong on up to 50% of occasions.     

Structural Topic Models for Open‐Ended Survey Responses

Collection and especially analysis of open‐ended survey responses are relatively rare in the discipline and when conducted are almost exclusively done through human coding. We present an alternative, semiautomated approach, the structural topic model (STM) (Roberts, Stewart, and Airoldi 2013; Roberts et al. 2013), that draws on recent developments in machine learning based analysis of textual data. A crucial contribution of the method is that it incorporates information about the document, such as the author's gender, political affiliation, and treatment assignment (if an experimental study). This article focuses on how the STM is helpful for survey researchers and experimentalists. The STM makes analyzing open‐ended responses easier, more revealing, and capable of being used to estimate treatment effects. We illustrate these innovations with analysis of text from surveys and experiments.     

Nazlı's photographic games: Said and art history in a contrapuntal mode

ABSTRACT

Through a focus on photographic portraits commissioned in the late nineteenth century by the Ottoman-Egyptian Princess Nazl? Han?m, Roberts analyses the ways they tested Ottoman and western conventions. An examination of Nazl?'s strategic engagement with photography in this period positions her within the often-separated domains of Egyptian nationalism, Ottoman political reform, western Orientalist art and a proto-feminist moment of Egyptian women's history. One of the striking things about the Nazl? portraits is their transgressive inventiveness. This is transgression as Edward Said defines it, with an emphasis on crossing boundaries, testing and challenging limits, and cutting across expectations. Nazl?'s inventiveness is apparent through her canny experimentation with the codes of portrait photography and the ways she deploys her portraits as tokens of exchange within her culture and with her European interlocutors. Roberts argues that Nazl? Han?m's use of photography operates in a contrapuntal mode in the Saidean sense of a simultaneity of voices that sound against, as well as with, each other. Over the last three decades Said's writings have provided a crucial methodological framework for the critique of western Orientalist visual culture. Recently art historians have repositioned this corpus of western imagery in relation to art by practitioners from the region and addressed cultural exchanges. Said's seminal text Orientalism has been pivotal within these debates. Yet it is not so much this landmark book, but rather Said's writings on music, in which we can find an alternative approach to cross-cultural exchange. By transposing this model into the domain of art history, Roberts engages with his notion of reading contrapuntally. Said was interested in the broader applicability of this term, although its potential as an interpretive model for the visual arts remains unexamined. Through this case study of Nazl? Han?m's photographs, Roberts reassesses the value of Said's writings on music for understanding nineteenth-century visual culture.     

Cambodia's uncertain future

Japanese government interests in Southeast Asia continue to expand. Official speeches refer to the growth of a ‘community that acts together’, while institutional linkages have been strengthened with the creation of the ASEAN Plus Three process and by a proliferation of bilateral arrangements. These developing networks raise questions about Japan’s future orientation towards its wider region. This article assesses recent developments, by challenging some of the fundamental assumptions about Japan’s regional behaviour. First, it examines how a tendency to render mutually exclusive bilateral and multilateral forms of behaviour serves to obfuscate a focus on the fundamental processes of regional engagement. Second, this article delineates Japan’s changing orientation towards the region as part of a process of ‘complex regional multilateralism’, in which a range of often ad hoc engagements have resulted in a loose framework for interaction. In so doing, it suggests that Japan’s current policy-making approach towards Southeast Asia may be regarded as a continuation of policy that is, nevertheless, being buffeted by a range of – primarily regional – external influences. The resulting set of perceived strategies demonstrates not an either/or approach to regional engagement but, rather, shows how the Japanese government manages changing circumstances to carve out a new role for itself in Southeast Asia.     

The Limits of Control: The Market State,Divided Power,and the Response to 9/11

ABSTRACT

The 9/11 attacks demanded a response from the U.S. government, but designing and executing that response was not easily done. The United States is an advanced market society in which power is highly dispersed. Federal policymakers were confronted with challenges that we now regard as typical of the network form of governance. Their ability to act decisively was constrained by public law, by the political influence and superior knowledge of private industry, and by widespread skepticism about the legitimacy of federal authority. While many commentators worried about the excessive concentration of power in the federal executive branch after 9/11, it might be more accurate to say that the post-9/11 period was typified by a prolonged, and often unsuccessful, effort to induce cooperation and coordination by a range of public and private actors.     

Using Paint to Investigate Fires: An ATR‐IR Study of the Degradation of Paint Samples Upon Heating

Fire investigation is a challenging area for the forensic investigator. The aim of this work was to use spectral changes to paint samples to estimate the temperatures to which a paint has been heated. Five paint samples (one clay paint, two car paints, one metallic paint, and one matt emulsion) have been fully characterized by a combination of attenuated total reflectance Fourier transform infrared (ATR‐IR), Raman, X‐ray fluorescence spectroscopy and powder X‐ray diffraction. The thermal decomposition of these paints has been investigated by means of ATR‐IR and thermal gravimetric analysis. Clear temperature markers are observed in the ATR‐IR spectra namely: loss of ν(C = O) band, >300°C; appearance of water bands on cooling, >500°C; alterations to ν(Si–O) bands due to dehydration of silicate clays, >700°C; diminution of ν(CO₃) and δ(CO₃) modes of CaCO₃, >950°C. We suggest the possible use of portable ATR‐IR for nondestructive, in situ analysis of paints.
