What does it mean “to lie” in an “honest village”?
Authors: Tutorskiy Andrey V. 
Published: December 2017

Cet article constitue une exploration du rôle joué par le mensonge dans la vie quotidienne et dans la construction identitaire en Russie européenne septentrionale. J’ai réalisé mon travail de terrain dans le village de Prokopiévo, dans le district d’Ustiany dans l’Oblast d’Arkhangelsk durant l’été 2014. L’intimité est le concept crucial sur lequel s’appuie cet article. La contradiction contenue dans ce concept est celle-ci : les relations d’intimité sont souvent perçues comme éternelles ou comme ayant des effets thérapeutiques. Mais, dans le même temps, elles suscitent des problèmes et des perturbations. Le mensonge est une pratique conspuée dans la Russie septentrionale. Les locaux favorisent une « culture de l’honnêteté ». A contrario, les étrangers, venus de la ville ou les migrants ruraux sont généralement perçus comme des menteurs. Ne pas dire la vérité à ce genre de menteurs (otnekivanie) est une pratique acceptable. Viveiros de Castro et Rupert Stasch ont récemment montré que ce style de fissures dans l’ordre communicatif est utilisé pour maintenir et consolider les relations de long court dans les petites communautés. Dans cet article, je souligne également le fait qu’il y a des pratiques au sein desquelles il est autorisé de mentir.
Designing a Resilience Program for Critical Care Nurses
Authors: Mealer Meredith , Hodapp Rachel , Conrad David , Dimidjian Sona , Rothbaum Barbara O. , Moss Marc 
Published: December 2017

Background:
Workplace stress can affect job satisfaction, increase staff turnover and hospital costs, and reduce quality of patient care. Highly resilient nurses adapt to stress and use a variety of skills to cope effectively.

Objective:
To gain data on a mindfulness-based cognitive therapy resilience intervention for intensive care unit nurses to see if the intervention program would be feasible and acceptable.

Methods:
Focus-group interviews were conducted by videoconference with critical care nurses who were members of the American Association of Critical-Care Nurses. The interview questions assessed the feasibility and acceptability of a mindfulness-based cognitive therapy program to reduce burnout syndrome in intensive care unit nurses.

Results:
Thirty-three nurses participated in 11 focus groups. Respondents identified potential barriers to program adherence, incentives for adherence, preferred qualifications of instructors, and intensive care unit-specific issues to be addressed.

Conclusions:
The mindfulness-based cognitive therapy pilot intervention was modified to incorporate thematic categories that the focus groups reported as relevant to intensive care unit nurses. Institutions that wish to design a resilience program for intensive care unit nurses to reduce burnout syndrome need an understanding of the barriers and concerns relevant to their local intensive care unit nurses.
Projets d’investissements miniers chinois dans l’arctique
Authors: Têtu Pierre-Louis , Lasserre Frédéric 
Published: December 2017

La Chine, premier importateur mondial de matières premières depuis le début du 21e siècle, est attentive au potentiel minier de l’Arctique. Des investissements directs à l’étranger (IDE) chinois dans des projets miniers dans l’Arctique canadien, le Grand Nord québécois et au Groenland ont contribué à faire naître une certaine sinophobie, en raison notamment de la méconnaissance des facteurs qui déterminent le choix de cette région pour ces investissements. Les résultats démontrent que ces territoires sont attrayants en raison de la stabilité politique et du climat compétitif des affaires qui les caractérisent, ainsi que de la qualité de leurs ressources physiques. En revanche, le manque d’infrastructures dans l’Arctique et le coût et la disponibilité de la main-d’oeuvre constituent des facteurs limitatifs.
Quels modèles de développement pour le Québec nordique?
Authors: Rodon Thierry , Therrien Aude 
Published: December 2017

Le Québec nordique a longtemps été perçu comme un réservoir de ressources pour le Sud et les populations autochtones qui l’habitaient étaient souvent ignorées. Le Plan Nord, lancé par Jean Charest en 2011, reprend cette même logique en mettant de l’avant le développement minier du territoire. Cependant, depuis les années 1970, on ne peut plus ignorer les droits des Autochtones et les régions du nord ont développé leurs propres institutions de gouvernance qui prennent part au développement régional en tentant de le redéfinir. Dans ce texte, après une comparaison des conditions socio-économiques des « nord » du Québec et de leur développement institutionnel, nous proposons une analyse des différents modèles de développement du Nord portés par les différents acteurs. Notre analyse s’appuie sur l’approche de la construction des nations (nation-building) développée par leHarvard Project on American Indian Economic Development.
Baroclinic instability in a reduced gravity,
three-dimensional, quasi-geostrophic model
Authors: RIPA P. 
Published: July 2002

The classical quasi-geostrophic model in an active layer with an arbitrary vertical
structure is modified by adding a boundary condition at the interface with a passive
(motionless) lower layer: the difference between isopycnal and interface elevations is a
Lagrangian constant, so that a particle in this boundary remains there and conserves
its density. The new model has the appropriate integrals of motion: in particular,
a free energy quadratic and positive definite in the deviation from a state with a
uniform flow, made up of the internal and ‘external’ potential energies (due to the
displacement of the isopycnals and the interface) and the kinetic energy.Eady's model of baroclinic instability is extended with the present system, i.e. including
the effect of the free lower boundary. The integrals of motion give instability
conditions that are both necessary and sufficient. If the geostrophic slope of the
interface is such that density increases in opposite directions at the top and bottom
boundaries, then the basic flow is nonlinearly stable. For very weak internal stratification
(as compared with the density jump at the interface) normal modes instability
is similar to that of a simpler model, with a rigid but sloping bottom. For stronger
stratification, though, the deformation of the lower boundary by the perturbation
field also plays an important role, as shown in the dispersion relation, the structure of
growing perturbations, and the energetics of the instability. The energy of long growing
perturbations is mostly internal potential, whereas short ones have an important
fraction of kinetic energy and, for strong enough stratification, external potential.
Threat perceptions and avoidance in recurrent dreams
Authors: Zadra A. , Donderi D. C. 
Published: July 2002

Revonsuo argues that the biological function of dreaming is to simulate threatening events and to rehearse threat avoidance behaviors. He views recurrent dreams as an example of this function. We present data and clinical observations suggesting that (1) many types of recurrent dreams do not include threat perceptions; (2) the nature of the threat perceptions that do occur in recurrent dreams are not always realistic; and (3) successful avoidance responses are absent from most recurrent dreams and possibly nightmares.[Hobson et al.; Revonsuo]
The role of competition and habitat in structuring small mammal communities in a tropical montane ecosystem in southern India
Authors: Shanker Kartik 
Published: July 2002

AbstractSmall mammals were sampled in two natural habitats (montane stunted evergreen forests and montane grassland) and four anthropogenic habitats (tea, wattle, bluegum and pine plantation) in the Upper Nilgiris in southern India. Of the species trapped, eight were in montane evergreen forests and three were in other habitats. Habitat discrimination was studied in the rodents Rattus rattus and Mus famulus and the shrew Suncus montanus in the montane forest habitat. Multivariate tests on five variables (canopy cover, midstorey density, ground cover, tree density, canopy height) showed that R. rattus uses areas of higher tree density and lower canopy cover. Suncus montanus and M. famulus use habitat with higher tree density and ground cover and lower canopy height. Multivariate tests did not discriminate habitat use between the species. Univariate tests, however, showed that M. famulus uses areas of higher tree density than R. rattus and S. montanus. Rattus rattus was the dominant species in the montane forest, comprising 60.9+ of total density, while the rodent Millardia meltada was the dominant species in the grassland. Studies of spatial interaction between these two species in habitats where they coexisted showed neither overlap nor avoidance between the species. Rattus rattus, however, did use areas of lower ground cover than did M. meltada. The analysis of spatial interactions between the species, habitat discrimination and use, and the removal experiments suggest that interspecific competition may not be a strong force in structuring these small mammal communities. There are distinct patterns in the use of different habitats by some species, but microhabitat selection and segregation is weak. Other factors such as intraspecific competition may play a more important role in these communities.
RAPD and isoenzyme analysis of genetic variability in three allied species of catfish (Siluriformes: Pimelodidae) from the Tibagi River, Brazil
Authors: de Almeida Fernanda Simões , Fungaro Maria Helena Pelegrinelli , Sodré Leda Maria Koelblinger 
Published: July 2002

AbstractGenetic variability in three species of Pimelodidae catfish (Iheringichthys labrosus, Pimelodus maculatus and Pimelodus cf. absconditus), collected at four sites in the Tibagi river‐basin: Sertaneja, Londrina (lower Tibagi), Sapopema (middle Tibagi) and Tibagi (upper Tibagi) was analysed using RAPD and isoenzymatic techniques. Iheringichthys labrosus had the greatest genetic variability showing a proportion of mean polymorphic loci (P̄m) of 53.7+. The dendrogram showed that the individuals from the locations were clustered together, supporting the hypothesis that I. labrosus has a sedentary or localized geographical distribution. Pimelodus maculatus is the only species studied that is considered to be highly migratory. The P̄m obtained for this species was 30.2+. Their genetic dendrogram showed that the individuals were not clustered, based on the place of collection. P. cf. absconditus had a P̄m value of 47.4+, and the external morphology of this species is similar to that of I. labrosus, which hindered differentiation of individuals from the two species. RAPD and isoenzyme analysis, however, provided differential patterns for P. cf. absconditus from I. labrosus.
Effects of radio‐collars on European badgers (Meles meles)
Authors: Tuyttens F. A. M. , Macdonald D. W. , Roddam A. W. 
Published: July 2002

AbstractThe relationships between radio‐collaring/tracking and 12 biometric parameters in a population of badgers (Meles meles) that were live‐trapped in south‐west England were investigated. The length of time for which a badger had worn a radio‐collar was selected as an explanatory variable in generalized linear models of three biometric parameters (body condition, body weight and testes volume) irrespective of whether or not age class was included as a variable in the analyses. There was evidence that badgers that had been carrying a radio‐collar for 1–100 days had lower body condition scores both when compared to badgers that had not been collared and with those that had been collared for longer than 100 days, suggesting a post‐collaring acclimation period. In addition, the time period between first and last capture was longer for radio‐collared than non‐collared badgers. It is unlikely that this was due to an effect of collaring on trappability or to non‐random selection of badgers for collaring. Although testes size differed between non‐collared badgers and badgers that had been tagged for > 100 days, the relationship between radio‐collaring and reproductive output remained unproven. These results highlight not only the need to assess the welfare aspects of radio‐collaring but also the potential intricacy of corollaries of collaring. Explorations such as that reported here are important to the validity of studies that make use of radio‐telemetry.
Plant 21D7 Protein, a Nuclear Antigen Associated with Cell Division, Is a Component of the 26S Proteasome

Published: July 2002

Abstract
Previously, we cloned a carrot (Daucus carota L.) cDNA encoding a 45-kD protein, 21D7, located in the nuclei of proliferating cells. The 21D7 protein is similar to the partial sequence of a regulatory subunit of the bovine 26S proteasome, p58 (G. DeMartino, C.R. Moomaw, O.P. Zagnitko, R.J. Proske, M. Chu-Ping, S.J. Afendis, J.C. Swaffield, C.A. Slaughter [1994] J Biol Chem 269: 20878–20884) and to the deduced sequence encoded by the Saccharomyces cerevisiae gene SUN2 (M. Kawamura, K. Kominami, J. Takeuchi, A. Toh-e [1996] Mol Gen Genet 251: [146–152]). In our work, the expression of plant 21D7 cDNA rescued the yeast sun2 mutant. Fractionation of carrot and spinach (Spinacia oleracea L.) crude extracts showed that the 21D7 protein sedimented with the active 26S proteasomes. The cessation of cell proliferation in carrot suspensions at the stationary phase caused 26S proteasome dissociation and, correspondingly, the 21D7 protein sedimented together with the free regulatory complexes of the 26S proteasomes. Large-scale purification of carrot 26S proteasomes resulted in coisolation of the 21D7 protein. Polyacrylamide gel electrophoresis under nondenaturing conditions showed that the 21D7 protein had the same mobility as the 26S proteasome and that proteasome dissociation changed the mobility of the 21D7 protein accordingly. We conclude that the 21D7 protein is a subunit of the plant 26S proteasome and that it probably belongs to the proteasome regulatory complex.
Calcium-Regulated Proteolysis of eEF1A
Authors: Ransom-Hodgkins Wendy D. , Brglez Irena , Wang Xuemin , Boss Wendy F. 
Published: July 2002

Abstract
Eukaryotic elongation factor 1α (eEF1A) can be post-translationally modified by the addition of phosphorylglycerylethanolamine (PGE). [14C]Ethanolamine was incorporated into the PGE modification, and with carrot (Daucus carota L.) suspension culture cells, eEF1A was the only protein that incorporated detectable quantities of [14C]ethanolamine (Ransom et al., 1998). When 1 mm CaCl2 was added to microsomes containing [14C]ethanolamine-labeled eEF1A ([14C]et-eEF1A), there was a 60% decrease in the amount of [14C]et-eEF1A recovered after 10 min. The loss of endogenous [14C]et-eEF1A was prevented by adding EGTA. Recombinant eEF1A, which did not contain the PGE modification, also was degraded by microsomes in a Ca2+-regulated manner, indicating that PGE modification was not necessary for proteolysis; however, it enabled us to quantify enodgenous eEF1A. By monitoring [14C]et-eEF1A, we found that treatment with phospholipase D or C, but not phospholipase A2, resulted in a decrease in [14C]et-eEF1A from carrot microsomes. The fact that there was no loss of [14C]et-eEF1A with phospholipase A2 treatment even in the presence of 1 mmCa2+ suggested that the loss of membrane lipids was not essential for eEF1A proteolysis and that lysolipids or fatty acids decreased proteolysis. At micromolar Ca2+ concentrations, proteolysis of eEF1A was pH sensitive. When 1 μmCaCl2 was added at pH 7.2, 35% of [14C]et-eEF1A was lost; while at pH 6.8, 10 μm CaCl2 was required to give a similar loss of protein. These data suggest that eEF1A may be an important downstream target for Ca2+ and lipid-mediated signal transduction cascades.
Complementary Expression of Two Plastid-Localized ς-Like Factors in Maize
Authors: Lahiri Sushmita D. , Allison Lori A. 
Published: July 2002

Abstract
The eubacterial-like RNA polymerase of plastids is composed of organelle-encoded core subunits and nuclear-encoded ς-factors. Families of ς-like factors (SLFs) have been identified in several plants, including maize (Zea mays) and Arabidopsis. In vitro import assays determined that at least two of the maize ς-like proteins have functional chloroplast transit peptides and thus are likely candidates for chloroplast transcriptional regulators. However, the roles of individual SLFs in chloroplast transcription remain to be determined. We have raised antibodies against the unique amino-terminal domains of two maize SLFs, ZmSig1 and ZmSig3, and have used these specific probes to examine the accumulation of each protein in different maize tissues and during chloroplast development. The expression of ZmSig1 is tissue specific and parallels the light-activated chloroplast development program in maize seedling leaves. Its accumulation in mature chloroplasts however, is not affected by subsequent changes in the light regime. It is interesting that the expression profile of ZmSig3 is complementary to that of ZmSig1. It accumulates in non-green tissues, including roots, etiolated seedling leaves, and the basal region of greening seedling leaves. The nonoverlapping expression patterns of these two plastid-localized SLFs suggest that they may direct differential expression of plastid genes during chloroplast development.
Analysis of the Ethylene Response in theepinastic Mutant of Tomato

Published: July 2002

Abstract
Ethylene can alter plant morphology due to its effect on cell expansion. The most widely documented example of ethylene-mediated cell expansion is promotion of the “triple response” of seedlings grown in the dark in ethylene. Roots and hypocotyls become shorter and thickened compared with controls due to a reorientation of cell expansion, and curvature of the apical hook is more pronounced. Theepinastic (epi) mutant of tomato (Lycopersicon esculentum) has a dark-grown seedling phenotype similar to the triple response even in the absence of ethylene. In addition, in adult plants both the leaves and the petioles display epinastic curvature and there is constitutive expression of an ethylene-inducible chitinase gene. However, petal senescence and abscission and fruit ripening are all normal in epi. A double mutant (epi/epi;Nr/Nr) homozygous for both the recessive epi and dominant ethylene-insensitive Never-ripe loci has the same dark-grown seedling and vegetative phenotypes as epi but possesses the senescence and ripening characteristics ofNever-ripe. These data suggest that a subset of ethylene responses controlling vegetative growth and development may be constitutively activated in epi. In addition, theepi locus has been placed on the tomato RFLP map on the long arm of chromosome 4 and does not demonstrate linkage to reported tomato CTR1 homologs.

Published: July 2002

The basic lectin from Artocarpus hirsuta specific towards methyl α-galactose has been purified and crystallized using the hanging-drop vapour-diffusion method with ammonium sulfate as precipitant. Three different crystal forms, orthorhombic I, orthorhombic II and hexagonal, were grown under the same crystallization conditions. The orthorhombic forms belonged to space group P212121 with unit-cell dimensions a = 92.9, b = 99.8, c = 166.2 Å and a = 89.9, b = 121.9, c = 131.6 Å, respectively. The unit-cell dimensions of the hexagonal form were a = b = 84.1 and c = 271.7 Å and the space group was P6122.

Published: July 2002

The X-ray crystal structure of native Scilla campanulata agglutinin, a mannose-specific lectin from bluebell bulbs and a member of the Liliaceae family, has been determined by molecular replacement and refined to an R value of 0.186 at 1.7 Å resolution. The lectin crystallizes in space group P21212 with unit-cell parameters a = 70.42, b = 92.95, c = 46.64 Å. The unit cell contains eight protein molecules of Mr
= 13143 Da (119 amino-acid residues). The asymmetric unit comprises two chemically identical molecules, A and B, related by a non-crystallographic twofold axis perpendicular to c. This dimer further associates by crystallographic twofold symmetry to form a tetramer. The fold of the polypeptide backbone closely resembles that found in the lectins from Galanthus nivalis (snowdrop) and Hippeastrum (amaryllis) and contains a threefold symmetric β-prism made up of three antiparallel four-stranded β-sheets. Each of the four-stranded β-sheets (I, II and III) possesses a potential saccharide-binding site containing conserved residues; however, site II has two mutations relative to sites I and III which may prevent ligation at this site. Our study provides the first accurate and detailed description of a native (unligated) structure from this superfamily of mannose-specific bulb lectins and will allow comparisons with a number of lectin–saccharide complexes which have already been determined or are currently under investigation.

Published: July 2002

Human rhinoviruses, the major cause of mild recurrent infections of the upper respiratory tract, are small icosahedral particles. Over 100 different serotypes have been identified. The majority (91 serotypes) use intercellular adhesion molecule 1 as the cell-attachment site; ten serotypes (the minor group) bind to members of the low-density lipoprotein receptor. Three different crystal forms of the minor-group human rhinovirus serotype 2 (HRV2) were obtained by the hanging-drop vapour-diffusion technique using ammonium sulfate and sodium/potassium phosphate as precipitants. Monoclinic crystals, space group P21, diffracted at least to 2.8 Å resolution, and two complete virus particles were located in the crystal asymmetric unit. A second type of crystals had a compact cubic like morphology and diffracted beyond 2.5 Å resolution. These crystals belong to a primitive orthorhombic space group, with unit-cell parameters a = 309.3, b = 353.5, c = 759.6 Å, and contain one virus particle in the asymmetric unit. A third type of crystals, with a prismatic shape and belonging to space group I222, was also obtained under similar crystallization conditions. These latter crystals, with unit-cell parameters a = 308.7, b = 352.2, c = 380.5 Å, diffracted to high resolution (beyond 1.8 Å) and contained 15 protomers per asymmetric unit; this requires that three perpendicular crystal twofold axes coincide with three of the viral particle's dyad axes.
