PRODUCTIVITY AND THE ENACTMENT OF A MACRO CULTURE
This paper reports the puzzling results of a study which examined IT capital investment
and productivity at three of the largest IT user sites in the U.S. for the period 1970-1990: Social
Security Administration (SSA), Internal Revenue Service (IRS), and the Federal Bureau of
Investigation (FBI). Based on detailed IT investment, employment, and output data over twenty
years, we found that only one agency had achieved significant productivity benefits, a second
agency had modest results, and a third agency achieved no results whatever. These results
cannot be explained by traditional theories of productivity of how productivity is produced.
We argue that IT-induced productivity results not simply from strategic choice, nor the
operation of the invisible hand in the market place, nor simply from keen managers adjusting
their organizations to an "objective" environment. Instead we propose instead a new theory in
which productivity benefits derive from a larger macro-culture enacted by powerful institutions
in an organizational field. We extend this analysis to the larger economy and examine how this
new theory helps us understand recent claims that IT is finally having positive productivity
benefits at the sector level, and also helps us understand how the current fascination with reengineering
and downsizing may be a self-fulfilling prophecy.Information Systems Working Papers Serie
Information Technology and Occupational Structure
A central tenet of much popular and scholarly
literature is that computers -and more broadly speaking
"information systems"- bring about significant change in
organizations. Some scholars focus on changes in
organizational structure- the division of labor and its
coordination through authority and power (Blau, 1976;
Danziger, et. d., 1982; Laudon, 1976; 1986; Keen 1981;
Kling and Iacono, 1984; Orlikowski and Robey, 1991;
Robey, 1981; Walton, 1989; Barley 1986; 1990) . Others
focus on IT induced changes in the design of work
(Zuboff, 1984; Bikson, et. al., 1985: Kraut, et. al., 1987;
Sproull and Kiesler, 199 1; Turner, 1984; Iacono and
Kling, 1987). Still others have argued that IT
significantly alters occupational structure in
organizations--the distribution of employment among
occupations and skill classes of workers (Braverman,
1984; Kling and Turner, 1987; Berndt, et. al., 1992;
Howell and W e , 1993; Cyert and Mowry, 1988; 1989).
In general, the impact of IT on occupational structure of
firms and organizations is a neglected area of empirical
research despite the fact that scholars have strong
opinions, and convincing theories, about such
occupational shifts.
In this paper we report the results of a twenty year
longitudinal study of occupational structure in three of the
largest and most intensive organizational users of IT in
the United States. For benchmarking purposes we also
examine occupational change at the aggregate society
level and in the federal government sector over a twenty
year period. The results of our research question the
claim that IT brings about significant change in
occupational structure. While the organizations we
examine did experience significant change in
occupational structure during periods of intense
computerization, these changes did not conform to
theoretical predictions and they were inconsistent from
one organization to another. We conc1ude that
organizational occupational structures are quite stable in
the face of massive IT change and claims that IT brings
about "revo1utionaryâ changes in organizational structure
have little empirical foundation even though there may be
isolated cases where such rapid and drastic changes do
occur.Information Systems Working Papers Serie
MANAGEMENT STRATEGY, INVESTMENT IN IT, AND PRODUCTIVITY
Previous literature on IT and productivity does not take into account different
organizational goals and different management strategies for achieving these goals. But
productivity and ROI relationships can easily differ as organizational goals and
management strategies differ. Therefore, we argue, it is no longer appropriate to ask,
"Does IT lead to productivity enhancement." or "Is the ROI on IT investments large or
small or nonexistent? The better question is under what conditions of organizational
climate and management choice does IT enhanced productivity result.
To illustrate the powerful effect of organizational goals and management strategy
on IT-productivity relationships, we examine the twenty year history of two of the largest
IT users in the world: the Internal Revenue Service and the Social Security
Administration. And we find that these two very similar agencies experienced very
different results from massive investments in IT despite sharing a similar production
function. There is nothing in micro economics however to explain the different strategies
pursed by these managers. Instead we must turn to political and sociological models of
organizations to understand the social construction of productivity results.Information Systems Working Papers Serie

Quasi‐2‐Day Wave in Low‐Latitude Atmospheric Winds as Viewed From the Ground and Space During January–March, 2020
Horizontal winds from four low-latitude (±15°) specular meteor radars (SMRs) and the Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) instrument on the ICON satellite, are combined to investigate quasi-2-day waves (Q2DWs) in early 2020. SMRs cover 80–100 km altitude whereas MIGHTI covers 95–300 km. Q2DWs are the largest dynamical feature of the summertime middle atmosphere. At the overlapping altitudes, comparisons between the derived Q2DWs exhibit excellent agreement. The SMR sensor array analyses show that the dominant zonal wavenumbers are s = +2 and + 3, and help resolve ambiguities in MIGHTI results. We present the first Q2DW depiction for s = +2 and s = +3 between 95 and 200 km, and show that their amplitudes are almost invariant between 80 and 100 km. Above 106 km, Q2DW amplitudes and phases present structures that might result from the superposition of Q2DWs and their aliased secondary waves
Air quality and error quantity: pollution and performance in a high-skilled, quality-focused occupation
We provide the first evidence that short-term exposure to air pollution affects the work performance of a group of highly-skilled, quality-focused employees. We repeatedly observe the decision-making of individual professional baseball umpires, quasi-randomly assigned to varying air quality across time and space. Unique characteristics of this setting combined with high-frequency data disentangle effects of multiple pollutants and identify previously under-explored acute effects. We find a 1 ppm increase in 3-hour CO causes an 11.5% increase in the propensity of umpires to make incorrect calls and a 10 mg/m3 increase in 12-hour PM2.5 causes a 2.6% increase. We control carefully for a variety of potential confounders and results are supported by robustness and falsification checks
Genome-wide association analysis implicates dysregulation of immunity genes in chronic lymphocytic leukaemia
Several chronic lymphocytic leukaemia (CLL) susceptibility loci have been reported; however, much of the heritable risk remains unidentified. Here we perform a meta-analysis of six genome-wide association studies, imputed using a merged reference panel of 1,000 Genomes and UK10K data, totalling 6,200 cases and 17,598 controls after replication. We identify nine risk loci at 1p36.11 (rs34676223, P=5.04 × 10−13), 1q42.13 (rs41271473, P=1.06 × 10−10), 4q24 (rs71597109, P=1.37 × 10−10), 4q35.1 (rs57214277, P=3.69 × 10−8), 6p21.31 (rs3800461, P=1.97 × 10−8), 11q23.2 (rs61904987, P=2.64 × 10−11), 18q21.1 (rs1036935, P=3.27 × 10−8), 19p13.3 (rs7254272, P=4.67 × 10−8) and 22q13.33 (rs140522, P=2.70 × 10−9). These new and established risk loci map to areas of active chromatin and show an over-representation of transcription factor binding for the key determinants of B-cell development and immune response

Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
The seeds of divergence: the economy of French North America, 1688 to 1760
Generally, Canada has been ignored in the literature on the colonial origins of divergence with most of the attention going to the United States. Late nineteenth century estimates of income per capita show that Canada was relatively poorer than the United States and that within Canada, the French and Catholic population of Quebec was considerably poorer. Was this gap long standing? Some evidence has been advanced for earlier periods, but it is quite limited and not well-suited for comparison with other societies.
This thesis aims to contribute both to Canadian economic history and to comparative work on inequality across nations during the early modern period. With the use of novel prices and wages from Quebec—which was then the largest settlement in Canada and under French rule—a price index, a series of real wages and a measurement of Gross Domestic Product (GDP) are constructed. They are used to shed light both on the course of economic development until the French were defeated by the British in 1760 and on standards of living in that colony relative to the mother country, France, as well as the American colonies.
The work is divided into three components. The first component relates to the construction of a price index. The absence of such an index has been a thorn in the side of Canadian historians as it has limited the ability of historians to obtain real values of wages, output and living standards. This index shows that prices did not follow any trend and remained at a stable level. However, there were episodes of wide swings—mostly due to wars and the monetary experiment of playing card money. The creation of this index lays the foundation of the next component.
The second component constructs a standardized real wage series in the form of welfare ratios (a consumption basket divided by nominal wage rate multiplied by length of work year) to compare Canada with France, England and Colonial America. Two measures are derived. The first relies on a “bare bones” definition of consumption with a large share of land-intensive goods. This measure indicates that Canada was poorer than England and Colonial America and not appreciably richer than France. However, this measure overestimates the relative position of Canada to the Old World because of the strong presence of land-intensive goods. A second measure is created using a “respectable” definition of consumption in which the basket includes a larger share of manufactured goods and capital-intensive goods. This second basket better reflects differences in living standards since the abundance of land in Canada (and Colonial America) made it easy to achieve bare subsistence, but the scarcity of capital and skilled labor made the consumption of luxuries and manufactured goods (clothing, lighting, imported goods) highly expensive. With this measure, the advantage of New France over France evaporates and turns slightly negative. In comparison with Britain and Colonial America, the gap widens appreciably. This element is the most important for future research. By showing a reversal because of a shift to a different type of basket, it shows that Old World and New World comparisons are very sensitive to how we measure the cost of living. Furthermore, there are no sustained improvements in living standards over the period regardless of the measure used. Gaps in living standards observed later in the nineteenth century existed as far back as the seventeenth century. In a wider American perspective that includes the Spanish colonies, Canada fares better.
The third component computes a new series for Gross Domestic Product (GDP). This is to avoid problems associated with using real wages in the form of welfare ratios which assume a constant labor supply. This assumption is hard to defend in the case of Colonial Canada as there were many signs of increasing industriousness during the eighteenth and nineteenth centuries. The GDP series suggest no long-run trend in living standards (from 1688 to circa 1765). The long peace era of 1713 to 1740 was marked by modest economic growth which offset a steady decline that had started in 1688, but by 1760 (as a result of constant warfare) living standards had sunk below their 1688 levels. These developments are accompanied by observations that suggest that other indicators of living standard declined. The flat-lining of incomes is accompanied by substantial increases in the amount of time worked, rising mortality and rising infant mortality. In addition, comparisons of incomes with the American colonies confirm the results obtained with wages— Canada was considerably poorer.
At the end, a long conclusion is provides an exploratory discussion of why Canada would have diverged early on. In structural terms, it is argued that the French colony was plagued by the problem of a small population which prohibited the existence of scale effects. In combination with the fact that it was dispersed throughout the territory, the small population of New France limited the scope for specialization and economies of scale. However, this problem was in part created, and in part aggravated, by institutional factors like seigneurial tenure. The colonial origins of French America’s divergence from the rest of North America are thus partly institutional
