Hunting and Weaving
Empiricism and Political Philosophy

(St Augustine’s Press, 2013)
ART 102

The essays in this volume honour the work of political scientist and Eric Voegelin scholar, Barry Cooper, by considering how political philosophy (a form of hunting) and empiricism get “woven” together (to borrow a metaphor from Plato). In other words, they consider how science needs to be conducted if it is to remain true to our commonsense experience of the world and to facilitate political judgment.

Several of the essays cover Eric Voegelin, including his understanding of consciousness, a comparison of him and Leo Strauss, and his self-understanding as a scholar. Other essays consider terrorism, technology, religion and the modern world, the divided line in Plato’s Republic, and the political significance of hope. The volume also includes a number of essays that consider different aspects of Canadian politics, including its strong regionalism, political culture, public law, and the infamous “Calgary School” of political science.

These essays are united by the concern that political science must “weave” together political philosophy and empiricism. This task was what Aristotle meant when he characterized political science as a matter of practical wisdom. It is an insight that was also central for Voegelin’s restoration of political science in the twentieth century, and that these essays continue into the twenty-first century.

Political analysis begins in whatever contemporary crisis the analyst has found himself. The analyst sifts through competing claims of political meaning asserted by the partisans in the crisis. From there he ascends to greater luminosity concerning the human condition by viewing those claims in light of the “major questions in the history of political thought.” They inform one another, as the search for order is necessarily the search for order that is conducted by a particular individual’s consciousness in the context of a particular community in space and time.

This volume will be of special interest to scholars of political philosophy as well as citizens and statesmen interested in how an engagement in the history of political philosophy can facilitate political judgment in particular political circumstances.

Mathematics-Tyson-SCI337

The Mathematics of Marriage
Dynamic Nonlinear Models

(MIT Press, 2002)
SCI 337

Divorce rates are at an all-time high. But without a theoretical understanding of the processes related to marital stability and dissolution, it is difficult to design and evaluate new marriage interventions. The Mathematics of Marriage provides the foundation for a scientific theory of marital relations. The book does not rely on metaphors, but develops and applies a mathematical model using difference equations. The work is the fulfillment of the goal to build a mathematical framework for the general system theory of families first suggested by Ludwig Von Bertalanffy in the 1960s. The book also presents a complete introduction to the mathematics involved in theory building and testing, and details the development of experiments and models. In one “marriage experiment,” for example, the authors explored the effects of lowering or raising a couple’s heart rates. Armed with their mathematical model, they were able to do real experiments to determine which processes were affected by their interventions.

Applying ideas such as phase space, null clines, influence functions, inertia, and uninfluenced and influenced stable steady states (attractors), the authors show how other researchers can use the methods to weigh their own data with positive and negative weights. While the focus is on modeling marriage, the techniques can be applied to other types of psychological phenomena as well.

Net-Nature-Jones-SCI337

“Net Transfer of Carbon between Ectomycorrhizal Tree Species in the Field,”

Nature, 388 (6642): 579-582, 07 August 1997

SCI 337

Different plant species can be compatible with the same species of mycorrhizal fungi and be connected to one another by a common mycelium. Transfer of carbon, nitrogen and phosphorus through interconnecting mycelia has been measured frequently in laboratory experiments, but it is not known whether transfer is bidirectional, whether there is a net gain by one plant over its connected partner, or whether transfer affects plant performance in the field. Laboratory studies using isotope tracers show that the magnitude of one-way transfer can be influenced by shading of ‘receiver’ plants fertilization of ‘donor’ plants with phosphorus, or use of nitrogen-fixing donor plants and non-nitrogen-fixing receiver plants indicating that movement may be governed by source–sink relationships. Here we use reciprocal isotope labelling in the field to demonstrate bidirectional carbon transfer between the ectomycorrhizal tree species Betula papyrifera and Pseudotsuga menziesii, resulting in net carbon gain by P. menziesii. Thuja plicata seedlings lacking ectomycorrhizae absorb small amounts of isotope, suggesting that carbon transfer between B. papyrifera and P. menziesii is primarily through the direct hyphal pathway. Net gain by P. menziesii seedlings represents on average 6% of carbon isotope uptake through photosynthesis. The magnitude of net transfer is influenced by shading of P. menziesii, indicating that source–sink relationships regulate such carbon transfer under field conditions.

Beyond the Barricades
Nicaragua and the Struggle for the Sandinista Press, 1979-1998

(Ohio University Press, 2002)
SCI 337

Throughout the 1980s, Barricada, the official daily newspaper of the ruling Sandinista Front, played the standard role of a party organ, seeking the mobilize the Nicaraguan public to support the revolutionary agenda. Beyond the Barricades, however, reveals a story that is both more intriguing and much more complex. Even during this period of sweeping transformation and outside military siege, another, more professional agenda also motivated Barricada’s journalists and editors.

When the Sandinistas unexpectedly fell from power in the 1990 elections, Barricada gained a substantial degree of autonomy that allowed it to explore a more balanced and nuanced journalism “in the national interest.” This new orientation, however, ran afoul of more orthodox party leaders, who gradually gained the upper hand in the bitter internal struggle that wracked the Sandinista Front in the early 1990s. The paper closed its doors in January 1998.

Adam Jones’s outstanding study offers an unprecedented behind-the-scenes looks at Barricada’s two decades of evolution and dissolution. It also presents an intimate portrait of a key revolutionary institution and the memorable individuals who were a part of it.

Integrated-Hanna-SCI337

Integrated Resource and Environmental Management
Concepts and Practice

(Oxford University Press, 2007)
SCI 337

The aim of this volume is to provide a coherent set of chapters that address major issues in resource and environmental management. The book has a North American focus with significant, but not exclusive Canadian Content. ‘Integration’ is the organizing theme of the volume. Integration as a concept (meaning variously integration across disciplines, across agencies, and across sectors) has been a key theme in the policy and management rhetoric of virtually every agency in North America and abroad for more than 30 years. As one of the dominant themes of the discipline, integration has been addressed both as a component and as the main focus of a variety of texts for this course. However, there is nothing on the market at the moment that is both up-to-date and North American in approach.

“Ring-opening radical clock reactions: many density functionals have difficulty keeping time”

Organic & Biomolecular Chemistry, 9(9), 3158.
SCI 337

The ability of several density-functional theory methods to describe the kinetics and energetics of a series of ring-opening reactions of cyclopropyl and cyclobutyl-type radicals was explored. PBE, B971 and B3LYP perform quite well in their ability to replicate experiment, based upon the ring opening of cyclopropylcarbinyl, two α-trialkylsilyloxycyclopropylmethyl radicals, pentamethylcyclopropylcarbinyl, cyclobutylcarbinyl and 1-cyclobutylethylcarbinyl. The other functionals tested, which includes BLYP, CAM-B3LYP, BHandHLYP, B2PLYP and B2PLYP-D, as well as functionals designed for kinetics applications, namely MPW1K, BMK and M06-2X, all perform poorly. The latter of these functionals display some integration grid dependencies.

AC-L-Strawberry-Buszard-SCI337

“‘AC-L’ Acadie’ Strawberry”
HortScience, 34(4): 743-744

SCI 337

‘AC-L’Acadie’ is a June-bearing strawberry cultivar (Fragaria × ananassa Duch.) bred by Shahrokh Khanizadeh, Bertrand Theriault, Odile Carisse and Deborah Buszard, and released in 1999 for Quebec and Eastern Central Canada growing conditions. ‘AC-L’Acadie’ produces large, firm fruit and the plants are moderately resistant to leaf diseases and partially resistant to the principal eastern races of red stele (Phytophthora fragariae Hickman). ‘AC-L’Acadie’ fruit store very well at room temperature for several days, making them ideal for shipping or for growers who need to store fresh fruit. The cultivar is recommended for pick-your-own and/or fresh-market producers. The Prefix “AC” in the name stands for “Agriculture and Agri-Food Canada.” The name ‘L’Acadie’ was chosen because this cultivar was originally selected at the L’Acadie substation of Agriculture and Agri-Food Canada and it was tested there for several years. This is also the site where much of the strawberry research and breeding is conducted in the province of Quebec.

Broadly-Science-Abbas-SCI337

“A Broadly Applicable Cross-linker for Aliphatic Polymers containing C–H Bonds”
Science, 366(6467): 875-878, 15 November 2019

SCI 337

Cross-linking a range of alkyl polymers: some alkyl polymers, such as polyethylene, can be cross-linked by using peroxides or high-energy radiation or through the addition of a radical forming agent. Others, like polypropylene, are likely to undergo chain scission, and this process tends to be uncontrolled in the distribution of the cross-links. Lepage et al. developed a widely applicable approach using bis-diazirine molecules as cross-linking agents (see the Perspective by de Zwart et al.). These molecules can be thermally or photochemically activated to form carbenes that readily insert into the polymer carbon-hydrogen bonds, thus leading to cross-linking. The bis-diazirine is nonexplosive, nonvolatile, and easily activated at relatively mild temperatures and thus could be used to fine-tune the properties of existing polymers through small chemical modifications.
