Saint Anselm on the Kingdom of Heaven: A Model of Right Order
John R. Fortin, O.S.B.
The Saint Anselm Journal , 2008,
Abstract: Although Saint Anselm never wrote a systematic treatise on heaven, the concept of heaven, as it is found in several of his writings, is robust; it is rich in meaning and content. All that is good and just, all that is blessing is included in the concept. Heaven is a sign of God's goodness and love for his angelic and human creatures. What stands out in Anselm's discussions of heaven is order: heaven is a model of right order. The paper will examine three kinds of order in the writings of Anselm that express his view of the order in heaven. First, there is the moral order in that sin and punishment are properly adjudicated by the work of the Son of God. Second, there is the salvific order in that heaven is the reward granted to those who persevere in the faith. Third, there is the mystical order in that heaven is to be inhabited by a perfect number of created beings. Thus when Anselm invokes heaven, as he does in many prayers and letters, he is invoking that which for him is a wonderful and powerful concept that reflects God's love.
Transport du linuron, de l'imidaclopride et du bromure au travers de colonnes de sol et de lysimètres drainants

Biotechnologie, Agronomie, Société et Environnement , 2000,
Abstract: Transport of linuron, imidacloprid and bromide along soil columns and field lysimeters. Undisturbed soil columns (65 cm high x 15 cm diam.) were used in a greenhouse experiment to study the effect of rainfall and mode of application on leaching pattern of linuron and imidacloprid. Two simulated rainfall amounts (288 mm and 496 mm) distributed over a one month period and two modes of application (sole or combined application of the two pesticides) were studied. Linuron did not leach below 65 cm of the soil columns. Imidacloprid was leached in trace amount below 65 cm soil columns (less than 1,5/ of applied a.i.). Under field conditions, linuron was detected in percolated water below 1 m depth lysimeters at concentration less than 4 microg per liter. Imidacloprid was detected at concentration less than 3 microg per liter in percolated water below 1 m depth. Bromide ion was leached at 62 to 88/ of the applied mass on soil columns or field lysimeters. The elution pattern of bromide ion suggests the presence of preferential flow paths.
Fermionic characters for graded parafermions
L. Bégin,J. -F. Fortin,P. Jacob,P. Mathieu
Mathematics , 2003, DOI: 10.1016/S0550-3213(03)00175-5
Abstract: Fermionic-type character formulae are presented for charged irreduciblemodules of the graded parafermionic conformal field theory associated to the coset $osp(1,2)_k/u(1)$. This is obtained by counting the weakly ordered `partitions' subject to the graded $Z_k$ exclusion principle. The bosonic form of the characters is also presented.

Rape as torture An evaluation of the Committee against Torture’s attitude to sexual violence
Katharine Fortin
Utrecht Law Review , 2008,
Abstract: This article evaluates whether the concerns expressed by feminist authors in the 1990s that the traditional construction of torture articulated in Article 1 of the Convention against Torture may prevent the Committee against Torture from adequately responding to sexual violence against women, in particular by non-state actors, are justified today. The first half of the article assesses how the Committee against Torture treats the ‘severe pain and suffering’ and ‘prohibited purpose’ requirements in the definition of torture in cases regarding violence against women. The second half of the article evaluates the Committee’s approach to violence against women by non-state actors. It does this by seeking to better understand how the Committee approaches the terms ‘acquiescence’ and ‘consent’ in the definition of torture in Article 1. An analysis of the Committee’s Conclusions and Recommendations indicates that it is willing to interpret the term acquiescence broadly so as to ensure that it is able to properly address violence against women by non-state actors.
Transfuguismo parlamentario en Guatemala: un caso de altos costos de asociación, monopolio partidario y bajos costos de transacción
Javier FORTIN
América Latina Hoy , 2010,
Abstract: RESUMEN: A diferencia del resto de países en Centroamérica, el alto índice de transfuguismo parlamentario ha generado un gran interés en Guatemala. En términos generales, el transfuguismo se ha visto como algo negativo con serias repercusiones sobre la representación, el sistema de partidos políticos y la democracia en general. En este artículo se propone una alternativa al tradicional estudio normativo del transfuguismo. Se sugiere que la consideración del diputado de migrar es una decisión estratégica orientada a maximizar su función de utilidad, donde el representante ambicioso hace un balance entre su capital, los recursos que recibe del partido político, los costos de asociación y los costos de transacción. Luego de analizar preliminarmente la unidad partidaria, la volatilidad electoral y de revisar varios casos de estudio, se propone que en Guatemala el transfuguismo se da por el monopolio partidario sobre los recursos colectivos y privados, por los altos costos de asociación y por los bajos costos de transacción. ABSTRACT: The high incidence of party switching has generated a lot of interest in Guatemala, something that has not happened in the rest of the Central American countries. Traditionally, party switching has been considered as something negative with serious repercussions over representation, political parties, and democracy. This article proposes an alternative to the common normative or prescriptive study of party switching. The argument is that switching is a strategic decision by congressmen in order to maximize their utility function; ambitious members of Congress will evaluate their own resources, the resources political parties are willing to offer, their association costs and their transaction costs. After a preliminary analysis of party unity, electoral volatility and a few case studies, the article suggests that switching in Guatemala is a function of parties’ monopoly over private and collective goods, of high association costs and low transactions costs.

The Connection between Low Income, Weak Labour Force Attachment and Poor Health
Fortin, Myriam
Canadian Studies in Population , 2010,
Abstract: Using 1994-2004 data from the National Population Health Survey, this papersheds light on the health situation of working-age Canadians and tests theconnection between low income, weak labour force attachment and poor healthusing logistic regressions. Results indicate that persistently poor or weaklyemployed Canadians are in much poorer health than other Canadians, and thatbeing persistently poor increases the probability of experiencing deteriorationin health as much as being in poor health increases the probability of becomingpoor, but that being persistently unemployed has an even stronger impact onhealth status. Résumé période allant de 1994 à 2004, cet article documente l’état de santé descanadiens en age de travailler et estime, grace à la régression logistique, laforce des liens entre faible revenu, faible effort de travail et mauvaise santé. Lesrésultats obtenus indiquent que les Canadiens qui sont, de fa on persistante,pauvres ou faiblement actifs sur le marché du travail sont en très mauvaisesanté comparé aux autres canadiens, que la pauvreté persistante accro t laprobabilité d’une détérioration de l’état de santé dans la même mesure qued’être en mauvaise santé accro t la probabilité de devenir pauvre, mais que detravailler peu ou proue, de fa on persistante, a un effet encore plus fort sur lasanté.
Explaining Geographic Gradients in Winter Selection of Landscapes by Boreal Caribou with Implications under Global Changes in Eastern Canada

Abstract: Many animal species exhibit broad-scale latitudinal or longitudinal gradients in their response to biotic and abiotic components of their habitat. Although knowing the underlying mechanism of these patterns can be critical to the development of sound measures for the preservation or recovery of endangered species, few studies have yet identified which processes drive the existence of geographical gradients in habitat selection. Using extensive spatial data of broad latitudinal and longitudinal extent, we tested three hypotheses that could explain the presence of geographical gradients in landscape selection of the endangered boreal woodland caribou (Rangifer tarandus caribou) during winter in Eastern Canadian boreal forests: 1) climate-driven selection, which postulates that geographic gradients are surrogates for climatic gradients; 2) road-driven selection, which proposes that boreal caribou adjust their selection for certain habitat classes as a function of proximity to roads; and 3) an additive effect of both roads and climate. Our data strongly supported road-driven selection over climate influences. Thus, direct human alteration of landscapes drives boreal caribou distribution and should likely remain so until the climate changes sufficiently from present conditions. Boreal caribou avoided logged areas two-fold more strongly than burnt areas. Limiting the spread of road networks and accounting for the uneven impact of logging compared to wildfire should therefore be integral parts of any habitat management plan and conservation measures within the range of the endangered boreal caribou. The use of hierarchical spatial models allowed us to explore the distribution of spatially-structured errors in our models, which in turn provided valuable insights for generating alternative hypotheses about processes responsible for boreal caribou distribution.
Optical suppression of drug-evoked phasic dopamine release

Abstract: Brief fluctuations in dopamine concentration (dopamine transients) play a key role in behavior towards rewards, including drugs of abuse. Drug-evoked dopamine transients may result from actions at both dopamine cell bodies and dopamine terminals. Inhibitory opsins can be targeted to dopamine neurons permitting their firing activity to be suppressed. However, as dopamine transients can become uncoupled from firing, it is unknown whether optogenetic hyperpolarization at the level of the soma is able to suppress dopamine transients. Here, we used in vivo fast-scan cyclic voltammetry to record transients evoked by cocaine and raclopride in nucleus accumbens (NAc) of urethane-anesthetized rats. We targeted halorhodopsin (NpHR) specifically to dopamine cells by injecting Cre-inducible virus into ventral tegmental area (VTA) of transgenic rats that expressed Cre recombinase under control of the tyrosine hydroxylase promoter (TH-Cre+ rats). Consistent with previous work, co-administration of cocaine and raclopride led to the generation of dopamine transients in NAc shell. Illumination of VTA with laser strongly suppressed the frequency of transients in NpHR-expressing rats, but not in control rats. Laser did not have any effect on amplitude of transients. Thus, optogenetics can effectively reduce the occurrence of drug-evoked transients and is therefore a suitable approach for studying the functional role of such transients in drug-associated behavior.
