In the years preceding the 1979 national elections, ideology featured prominently in political debates and consultations regarding the new constitutional order. Proponents of a social democratic system were particularly prominent. However, the actual formation of political parties, governed by the new requirements for national representation, and the resurgence of veteran...
The 1979 Nigerian elections reflected the dedication of Nigerians to pursue democratic governance and the severe challenges to be overcome. The sweeping victory of the NPN, and the election of Alhaji Shehu Shagari as president, required a last-minute manipulation of the formula for achieving victory in the first round. After...
The building of a trans-ethnic political space, and a nation that commands the loyalty of the country’s citizens, have been persistent aspirations of Nigerian governments. The 1979 elections demonstrated that, however much political party leaders may seek to build a national following, they are “trapped” by ethnic and other sectional...
The building of the Second Republic required a military government, which had been deeply engaged in shaping the Federation over almost fifteen years, performing as an impartial umpire in the electoral choice of its successors. This complex process is dissected in this article together with an analysis of the relative...
This article resumes the exploration of Nigeria’s political economy and the entrenchment of a prebendal mode of attitudes and behaviors. It takes up the shift to a mono-mineral export economy, the socio- economic proclivities of the dominant class, the considerable expansion in the state’s economic role, and the distinct pattern...
The forcible ending of Nigeria’s second attempt at constitutional civilian rule since independence in 1960 is a mixed story. The 1983 general elections were tarnished by violence and fraud. They took place in a context of economic decline and policy disarray. However, the opposition still retained an important share of...
In this essay, key features of Nigerian governance since independence are reviewed. The military had ruled the county for thirteen years and civilian politicians, in two phases, had done so for ten. Military governments involved significant participation by civilians, so there was overlap between these successive systems. Moreover, the military...
The custom of voluntarily tipping for services rendered has gone in and out of fashion in America since its introduction in the 19th century. Restaurant owners that ban tipping in their establishments often claim that social justice drives their decisions, but we show that rational profit-maximization may also justify the...
Cracking is one of the most common concerns cited by owners of structures adjacent to construction or mining blasting. While a large database of case studies documenting the relative insignificance of ground motion induced by responsible blasting compared to weather effects on cracks in nearby structures has been established, the...
Most studies of crack response have focused on opening and closing of a crack in the plane of the wall in which the crack occurs. Crack movement also occurs perpendicular or normal to the plane of the wall. This paper will examine and compare the in-plane and out-of-plane (normal) response...
Surveillance of large geotechnical projects requires autonomous collection of data from a wide range of instrument types. An equally large range of data formats are employed by these measurement systems. A data exchange protocol is needed to make field data available for interpretation on a variety of platforms. This paper...
Blasting and climatological response of cracks are compared for structures constructed of concrete block typical of home construction in Europe. While much has been written comparing micrometer crack response of wood frame structures typical of residential construction in North America, little has been written concerning response of structures more typical...
Carbonation, a neutralizing reaction in cement paste, can be used to date cracks in cementitious materials. Currently, comparison between two cracks is the only method available to predict a relative age with carbonation. These two crack studies require a crack of known age in a similar material with similar exposure...
This paper summarizes micro-inch response of cosmetic cracks in a typical slab-ongrade ranch style house to both construction equipment-induced vibration and environmental (weather) effects. This structure was instrumented, and its response studied as part of the development of an Autonomous Crack Measurement (ACM) system. ACM systems are intended to record...
Concern over construction vibration-induced cracking has led to development of a new approach to vibration monitoring called autonomous crack measurement (ACM) and illustrated in Figure 1. This paper describes the concept as well as sensor performance in the first test house fitted an ACM system. Response of three cracks in...
There have been numerous studies that have aimed at improving the low tensile strength, stiffness, and toughness of cementitious materials. This study aims to show that all of these characteristics can be greatly improved by the addition of ladder scale reinforcement at the nano and micro scale. Carbon nanofibers (CNFs)...
Neuroscience research has made many important contributions to the study of the brain and behavior. Perhaps because of these contributions the general public seems to be easily seduced by neuroscientific explanations. Meaning that when a scientific article is paired with a brain image, the information within the article is automatically...
Which areas of Chicago have greater concentrations of lead in their water and is that associated with environmental racism? Since Chicago is racially segregated, the marginalized areas such as the south side and west side are more likely to contain high levels of lead.
Humans are unique in their ability to think abstractly (e.g. using language, learning relations). Previous work from our lab has shown that infants can learn simple abstract relations, like whether two objects are the “same” or “different”. In this study, we investigated flexibility in early learning. Our question was whether...

Research questions: Do students face pressure to choose certain racial identities in different social spheres on campus? What identities are selected in what situations? What struggles are faced by those of more than one race on Northwestern’s campus? What privileges are associated with being a multi-racial student at Northwestern University?...
As many systems of military and autocratic rule came under challenge in Africa, Nigeria lost its leadership position in a democratizing era with the collapse of the Second Republic, 1979-1983. Four military heads-of-state followed. One of the most hopeful transitional experiments in Africa, conducted under General Ibrahim Babangida, 1985-1993, ended...
An address delivered at the launching of the Nigerian edition of my book on prebendalism published by Spectrum Books (Ibadan), at the Nigerian Institute of International Affairs. It appeared in print in The Guardian (Lagos), June 5, 1991.
The suitability of the term “crucible” to capture the dilemmas of Nigeria is evident in this unpublished paper. After Ibrahim Babangida supplanted Muhammadu Buhari as the head-of-state in August 1985, Nigeria entered an arena of experimentation in several regards. Babangida is arguably the most dynamic, skilfull and charismatic leader in...
In this article, a Nigerian military system of governance is explicated. It was the dominant mode of governance in Nigeria until civilian rule was restored in 1999, initially under a former military ruler. Starting from the first military coup in January 1966, Nigeria experienced over 33 years of this system,...
This paper was written at the midway point in the governing of Nigeria by a paradoxical individual, Ibrahim Babangida. It should provoke further studies of his 8-year rule, 1985-1993, that seemed transformative during much of this period but ended in disarray and disappointment. The ideological orientation of the Nigerian economy;...
A long-running wager took place between the Babangida regime (1985-1993) and Nigerian civic, professional and political groups that the former would honor its commitment to usher in a Third Republic via free and fair elections. The June 12, 1993 elections were as free, fair and competently administered as could be...
When this testimony was given, there was still hope that Ibrahim Babangida would transfer the presidency to the elected Moshood Abiola before he left office on August 27, 1993. In that way, Nigeria would join the wave of post-Cold War democratizing nations. I had earlier called for a “transition in...
More than taking Nigeria back into the “dismal tunnel” of military rule, after seizing power in November 1993, Sani Abacha raced through the playbook he knew as a senior member of Babangida’s junta. Like Babangida, he pushed back the announced date for the return to civilian rule, launched an exercise...
This revised version of a paper presented at a conference at M.I.T. on State, Conflict, and Democracy in 1997 pulled together key dimensions of a Nigeria that had drifted far from constitutional and democratic governance. State and society had become increasingly criminalized; the educational system and other social sectors were...
This opinion piece, written by two long-term students of Nigerian politics, proposed a different course to the one taken following the death in mid-1998 of a military tyrant and the elected president he had imprisoned. It called for the creation of a caretaker national government of respected civilians that would...
This is the text of a public address at the Nigerian Institute of International Affairs delivered soon after the inauguration of Nigeria’s Fourth Republic. It identified several priorities after fifteen and a half years of military government. The country’s eroded legislative, judicial, and other state institutions needed to be rebuilt...
In many dryland environments, vegetation self-organizes into bands that can be clearly identified in remotely-sensed imagery. The status of individual bands can be tracked over time, allowing for a detailed remote analysis of how human populations affect the vital balance of dryland ecosystems. In this study, we characterize vegetation change...
It is becoming increasingly evident that the nanoscale organization and structure of macromolecules play a significant role in determining the function and properties of biological systems. To understand the relationships between biological structure and function at nanometer length scales, there is a need for methods which enable imaging of intact...
Georg Friedrich Haas composed in vain in reaction to political events in his native Austria. The piece is well known for making use of clashing tuning systems and darkness in the concert hall. These two facets of Haas’s writing have been much discussed and written about. The political dimension of...
Beethoven’s late compositional style is known for bending conventions he learned as a young man. Many discussions of his late style concentrate on adherence to and deviations from the conventions of functional harmony, fugal techniques, and sonata form. This document sheds light on an additional, previously unexamined aspect of Beethoven’s...
Kaija Saariaho’s vocal music offers singers a rewarding challenge. Her works contain extended techniques and innovative performance practices, which allow her to create interesting and moving timbral effects. Her musical language has its foundation in her cultural identity, formed when she was a girl in the forests of Finland. The...
Chaya Czernowin’s opera 'Pnima…ins innere' is about the encounter between a young Israeli boy and his grandfather, a Holocaust survivor so traumatized by his past that he cannot speak. Fittingly, the opera does not contain any words: the four singers in the work instead sing phonemes and other non-verbal sounds....
Ever since Jean-Baptiste Lully welcomed the horn to the stage as an instrument capable of producing music suitable for indoors, a tradition of horn methodology and pedagogy has been developed and expanded over the centuries. Despite the volume and variety of pedagogical materials available to the horn student and pedagogue...
Starting in the late 1950s, the advertising world rapidly became a fertile arena for experimentation in the realm of electronic music. Composers explored new forms, such as the sound logo; new technology, such as the Moog synthesizer; and new semiotic relationships between music, words, images and concepts, including attempts to...
Since the standardization of the modern brass quintet in the middle of the twentieth century, extensive research has been dedicated to the history of the genre, ensembles which have promoted and advanced brass chamber music and the growing body of original brass quintet repertoire. Such scholarship has provided practical benefits...
Since Ottorino Respighi included the recording of a nightingale in his Pini di Roma (1924), composers have used prerecorded nature sounds, or field recordings, to help establish a specific sense of place. The purpose of this project is to examine how modern composers utilize field recordings to create natural-world settings,...

Stroke is the leading cause of death and long term disability in the industrialized world. With the current population aging, the number of individuals at risk of stroke along with the associated health care costs are anticipated to rise considerably in the coming years. Consequently, there is an unmet need...
The first chapter of this dissertation develops a two-stage inference method for structural parameters in the linear instrumental variables model. In the first stage, a new statistic is used to detect whether the correlation between the structural error and the reduced form error is small. In the second stage, a...
The behavior of type-II superconductors is modeled using the time-dependent Ginzburg Landau equations (TDGLE). Pinning centers (inclusions) and geometries which maximize the critical current that can be passed through a superconductor are numerically obtained. Previous analytical results are summarized and new results are obtained for the critical current in one...
Refugees gain access to benefits and services in the United States through the bureaucratic birthdates recorded in the documents they carry when they first enter the country. Examining how and why chronometric age based on these documents was essential to resettlement was the starting point for my dissertation, which explores...
Anisotropic semiconducting thin films have attracted attention in recent years for important applications such as electrical interconnects, electronic sensors, field-emission devices and thermoelectric devices. However, the characterization of the full conductivity tensor, especially the cross-plane conductivity, remains a great challenge for anisotropic thin films. In addition, the synthesis of large-area...
Meeting the exploding demand for wireless data services will require access to new wireless spectrum. However, the traditional approach of clearing spectrum and reallocating is becoming increasingly difficult. This in turn has led to much interest in new approaches for sharing spectrum among different users, such as the those being...
Pattern recognition-based myoelectric control of upper limb prostheses has been made clinically available to individuals with more proximal upper limb amputations and can restore intuitive control of a prosthetic hand. This control method has yet to be implemented for individuals with amputations distal to the wrist (i.e. partial-hand amputations) and...
We study analytic functions on the open unit p-adic poly-disk centered at the multiplicative identity and prove that such functions only vanish at finitely many n-tuples of roots of unity unless they vanish along a translate of the formal multiplicative group. (Note that a root of unity lies on the...
Using Eynard-Orantin topological recursion, we prove here a result concerning the equivariant Gromov-Witten invariants for the projective line equipped with the standard action of the 2-torus. Our result is that the genus g, n point Gromov-Witten potential with arbitrary primary insertions may be written as a sum over certain genus...
Plasmonic nanostructures can confine light at their surface in the form of surface plasmon polaritons (SPPs) or localized surface plasmons (LSPs) depending on their geometry. SPPs are excited on nano- and micropatterned surfaces, where the typical feature size is on the order of the wavelength of light. LSPs, on the...
Catalyzed by the invention of magnetic tape recording, audio production has transformed from technical to artistic, and the roles of producer, engineer, composer, and performer have merged for many forms of music. However, while these roles have changed, the way we interact with audio production tools has not and still...
Data mining for materials discovery is concerned with representing materials science problems into a statistical framework, and learning models that describe observations about the processing, structure, and property of materials. The type of materials includes metals, ceramics, glass, polymers, and composites which are mixtures of multiple types. Observations come from...
Consent is at the center of feminist politics and theory; the importance of this concept is evident in the recent campus activism around sexual assault. Because consent has become so critically important, it is necessary for feminists to interrogate the concept of consent. In this dissertation, I argue that consent...
Myocardial perfusion is an important marker of cardiovascular health that is routinely evaluated clinically. Perfusion is measured most often using single photon emission computed tomography (SPECT) imaging, but magnetic resonance imaging (MRI) has many advantages over SPECT. Measuring perfusion quantitatively in ml/min/g would theoretically allow for improved characterization of cardiac...
The growth of incarceration in the United States, a symptom of the concomitant broader institutionalization of a ‘carceral state’, is unquestionably one of the most significant developments in the nation's history. Despite this significance, the public response to the growth and deleterious consequences of incarceration has been notably restrained. This...
Pattern recognition algorithms have been proposed as a way to control powered lower limb prostheses, specifically for transitioning between the different pre-programmed locomotion modes of the prosthesis (e.g., level ground walking, stair ascent, etc.). However, these algorithms cannot track changes in the statistical characteristics of input signals, and do not...
