Purpose

Previous research has demonstrated relationships of social support with disease-related biomarkers in patients with ovarian cancer. However, the clinical relevance of these findings to patient outcomes has not been established. This prospective study examined how social support relates to long-term survival among consecutive patients with ovarian cancer. We focused on two types of social support: social attachment, a type of emotional social support reflecting connections with others, and instrumental social support reflecting the availability of tangible assistance.

Patients and Methods

Patients were prospectively recruited during a presurgical clinic visit and completed surveys before surgery. One hundred sixty-eight patients with histologically confirmed epithelial ovarian cancer were observed from the date of surgery until death or December 2010. Clinical information was obtained from medical records.

Results

In a Cox regression model, adjusting for disease stage, grade, histology, residual disease, and age, greater social attachment was associated with a lower likelihood of death (hazard ratio [HR], 0.87; 95% CI, 0.77 to 0.98; P = .018). The median survival time for patients with low social attachment categorized on a median split of 15 was 3.35 years (95% CI, 2.56 to 4.15 years). In contrast, by study completion, 59% of patients with high social attachment were still alive after 4.70 years. No significant association was found between instrumental social support and survival, even after adjustment for covariates.

Conclusion

Social attachment is associated with a survival advantage for patients with ovarian cancer. Clinical implications include the importance of screening for deficits in the social environment and consideration of support activities during adjuvant treatment.
Sulfur dioxide derivatives improve the vasorelaxation in the spontaneously hypertensive rat by enhancing the vasorelaxant response to nitric oxide

Published: July 2012

The present study was designed to explore the role of sulfur dioxide (SO2) in the regulation of vasorelaxation in the spontaneously hypertensive rat (SHR). Twenty-two Wistar rats and 15 SHRs were divided randomly into the following groups: Wistar-Kyoto (WKY) control ( n = 8), WKY+Na2SO3/NaHSO3 ( n = 8), WKY+l-aspartic acid- β-hydroxamate (HDX) ( n = 6), SHR control ( n = 8) and SHR+Na2SO3/NaHSO3 ( n = 7). Their blood pressure in vivo was measured by tail plethysmography. The vasorelaxant response of the thoracic aorta to acetylcholine (Ach) and sodium nitroprusside (SNP) in all rats was tested, respectively, in the experiment. At the same time, the SO2 content of the WKY aorta after incubation with HDX and the vasorelaxant response to Ach after incubation with HDX were quantified. Nitric oxide (NO) production in the aorta of all rats was determined. We also measured the vasorelaxant responses of WKY aorta to different concentrations of SO2 after incubation with the NO inhibitor, NG-nitro-l-arginine methyl ester (l-NAME). The blood pressure decreased significantly in SHRs treated with SO2 derivatives ( P < 0.05). Reduction of endogenous SO2 in WKY vessels resulted in a decrease in the vasorelaxation induced by Ach. Vasorelaxation in response to both Ach and SNP increased in SHRs treated with SO2 derivatives compared with SHR controls, but decreased in WKY given HDX compared with WKY controls ( P < 0.05). The NO level in arterial tissues increased in SHRs treated with SO2 derivatives ( P < 0.05). However, the vasorelaxant response to SO2 derivatives in the presence of l-NAME decreased markedly compared with WKY controls. The results suggest that SO2 reduced blood pressure and increased vasorelaxation in SHR arteries via enhancing the vasorelaxant response to NO in isolated aortic rings and increasing the NO level of aortic tissues.

We report prevalence of Treponema pallidum (TP) seropositivity and herpes simplex virus type 2 (HSV-2) infection and risk factors associated with their prevalence in a cohort of men who have sex with men (MSM) in Bangkok, Thailand. Between April 2006 and March 2010 we enrolled Thai MSM into a cohort study based at the Silom Community Clinic, with baseline behavioural data and laboratory testing for sexually transmitted infections (STIs). Logistic regression was used to analyse risk factors associated with the prevalence of TP seropositivity and HSV-2 infection. From a total of 1544 enrolled men (mean age 26 years) TP, HSV-2 and HIV seropositive rates were 4.4%, 20.7% and 21.6%, respectively. After multivariable analysis, participating in group sex, reporting paying for sex, reporting sex with a casual partner in a park and being HSV-2 seropositive were associated with TP prevalence. Age ≥30 years, having less than a high school education, past use of recreational drugs, meeting casual sexual partners at a public venue (sauna) and TP seropositivity were associated with HSV-2 infection. The significant baseline prevalence of TP seropositivity and HSV-2 infection in this cohort demonstrates the need for screening and treatment of these STIs and targeted prevention interventions in Thai MSM in Bangkok.
Risk factors for male patients with gonorrhoea complicated by inflammation of the paraurethral glands around the external urethral orifice
Authors: Fan W , Zhang Q
Published: July 2012

Gonococcal inflammation of paraurethral glands around the external urethral orifice is a local complication of gonorrhoea in men. To investigate the risk factors for this complication we compared prepuce factors, Chlamydia trachomatis infection, demographic data and behavioural indicators of gonorrhoeal patients with and without this complication. Results showed that a prolonged disease course of gonorrhoea, sexual intercourse during gonorrhoea, repeated squeezing of the penis and a redundant prepuce were risk factors for this complication.

Published: July 2012

OBJECTIVE:

To examine the relationship between local macroeconomic indicators and physical abuse admission rates to pediatric hospitals over time.

METHODS:

Retrospective study of children admitted to 38 hospitals in the Pediatric Hospital Information System database. Hospital data were linked to unemployment, mortgage delinquency, and foreclosure data for the associated metropolitan statistical areas. Primary outcomes were admission rates for (1) physical abuse in children <6 years old, (2) non-birth, non-motor vehicle crash-related traumatic brain injury (TBI) in infants <1 year old (which carry high risk for abuse), and (3) all-cause injuries. Poisson fixed-effects regression estimated trends in admission rates and associations between those rates and trends in unemployment, mortgage delinquency, and foreclosure.

RESULTS:

Between 2000 and 2009, rates of physical abuse and high-risk TBI admissions increased by 0.79% and 3.1% per year, respectively (P ≤ .02), whereas all-cause injury rates declined by 0.80% per year (P < .001). Abuse and high-risk TBI admission rates were associated with the current mortgage delinquency rate and with the change in delinquency and foreclosure rates from the previous year (P ≤ .03). Neither abuse nor high-risk TBI rates were associated with the current unemployment rate. The all-cause injury rate was negatively associated with unemployment, delinquency, and foreclosure rates (P ≤ .007).

CONCLUSIONS:

Multicenter hospital data show an increase in pediatric admissions for physical abuse and high-risk TBI during a time of declining all-cause injury rate. Abuse and high-risk TBI admission rates increased in relationship to local mortgage delinquency and foreclosure trends.
The paranoia of data collection in Hungary and the health system
Authors: Gresz Miklós
Published: July 2012

There is no integrated national health database in Hungary. The currently available database collects only important parameters relevant for funding, and these include data only from publicly funded providers. Patient data in different hospitals are inaccessible from outside but, because of insufficient filing and closures of hospitals, they are often not available in the hospital either. The author encourages to establish a medical database in Hungary by showing foreign examples, thus providing both medical staff and research with authentic patient data. Orv.

Background: Rheumatoid arthritis (RA) and chronic periodontitis (CP) are the most common chronic inflammatory diseases and have remarkable similar pathologies. The aim of this study is to investigate the impact of periodontal status on oxidative stress in patients with RA by evaluating serum oxidative parameters and prolidase levels.

Methods: For this cross‐sectional comparative study, the following four groups were composed of 20 individuals each (80 individuals total): 1) RA with CP (RA‐CP group); 2) RA but periodontally healthy (RA‐C group); 3) systemically healthy with CP (CP group); and 4) systemically and periodontally healthy (C group). Demographic, periodontal, rheumatological, and serum oxidative parameters as determined by serum total antioxidant status, total oxidant status, oxidative stress index (OSI), lipid hydroperoxide levels, paraoxonase, arylesterase, and ceruloplasmin activity, prolidase level, and total sulfhydryl groups were evaluated.

Results: The OSI values of the RA‐CP group were statistically significantly higher than those of the C group (P <0.05). The prolidase levels of the RA‐C, RA‐CP groups and the CP group were statistically higher than those of the C group (P = 0.001, P = 0.007, and P = 0.001, respectively).

Conclusions: Although CP and RA each increase oxidative stress, in a small sample size these effects are only significant when both CP and RA are combined relative to neither exposure. In addition, increased prolidase levels in patients with RA and CP may be related to increased oxidative tissue damage.
Foolproof eternal domination in the all-guards move model
Authors: Klostermeyer William , MacGillivray Gary
Published: July 2012

The eternal domination problem requires a graph be protected against an infinitely long sequence of attacks at vertices, by guards located at vertices, with the requirement that the configuration of guards induces a dominating set at all times. An attack is defended by sending a guard from a neighboring vertex to the attacked vertex. We allow all guards to move to neighboring vertices in response to an attack, but allow the attacked vertex to choose which neighboring guard moves to the attacked vertex. This is the all-guards move version of the “foolproof” eternal domination problem that has been previously studied. We present some results and conjectures on this problem.
A representation of weak effect algebras
Authors: Chajda Ivan
Published: July 2012

Weak effect algebras were introduced by the author as a generalization of effect algebras and pseudoeffect algebras. It was shown that having a basic algebra, we can restrict its binary operation to orthogonal elements only and what we get is just a weak effect algebra. However, the converse construction is impossible due to the fact that the underlying poset of a basic algebra is a lattice which need not be true for weak effect algebras. Hence, we found a weaker structure than a basic algebra which can serve as a representation of a weak effect algebra.
Partial information systems and the Smyth powerdomain
Authors: Hart James
Published: July 2012

The dual of the join semilattice of proper compact Scott open subsets of a domain D is called the Smyth powerdomain of D. The Smyth powerdomain is used in programming semantics as a model for demonic nondeterminism. In this paper, we introduce the concept of partial information systems; and, as an application, show that the Smyth powerdomain of any domain can be realized in terms of the sub partial information systems of the domain’s corresponding information system.
Torsion classes of abelian cyclically ordered groups
Authors: Jakubík Ján
Published: July 2012

We introduce the notion of torsion class of abelian cyclically ordered groups; the definition is analogous to that used in the theory of lattice ordered groups. The collection T of all such classes is partially ordered by the class-theoretical inclusion. Though T is a proper class, we can apply the usual terminology for this partial order. We prove that T is a complete, infinitely distributive lattice having infinitely many atoms.

Elimination of the type B uncertainty
Authors: Kubáček Lubomír
Published: July 2012

An uncertainty of an estimated parameter can be, in general, decomposed into two parts, i.e. an uncertainty caused by errors in the actual experiment (the type A uncertainty) and an uncertainty caused by errors in preceding experiment, where some wanted constants were estimated (the type B uncertainty). These constants are necessary for an estimation of the useful parameters.

The aim of the paper is to find a condition for elimination of the type B uncertainty.

Accumulation of Total Anthocyanins in Wheat Grain

In the recent years, for specific goals of utilization, winter wheat breeding has been aimed on increasing total anthocyanins concentration in winter wheat grains considering their high antioxidant activity. The aim of research was to evaluate grain colour development in four wheat genotypes (ANK 28A and 62/0 purple pericarp, UC 66049 blue aleurone and Ilona red pericarp) during grain filling period. Grain samples from two replications of field experiment, established in the vegetation 2010/11, were taken in five to six sampling times. Total anthocyanins concentration was determined by spectrophotometer. The genotypes responded differently to the dynamics of total anthocyanins accumulation during grain filling. The process was described by linear and also by polynomial regression on the number of days post anthesis. Genotypes with purple pericarp reached the highest total anthocyanins concentration on the 22ndday post anthesis with increasing and decreasing before and after this sampling time, respectively. At maturity the highest total anthocyanins had UC 66049 (193.38 mg/kg). Newly bred genotype 62/0 had similar concentration (34.50 mg/kg) as its parent ANK 28A (37.80 mg/kg). At maturity, registered cultivar Ilona was about 93.7% lower in total anthocyanins concentration compared to ANK 28A. Significant variability in total anthocyanins concentration indicated that breeding for their increasing is possible.

Sodium Azide Induced Morphological and Molecular Changes in Persimmon (Diospyros LotusL.)

PersimmonDiospyros lotusL. is an underutilized species, used as rootstock for Japanese persimmon (Diospyros kakiThunb.) in many European countries. It has a potential for ornamental uses due to its diploid genome that suggests an easy mutation induction. This study was aimed at unravelling the effects of mutagenic sodium azide (in concentrations of 0.1% and 0.5%) on morphological characters (plant height, maximal leaf blade length, maximal leaf blade width and leaf petiole length) and molecular relations of treated accessions, based on AFLP (amplified fragment length polymorphism). In the M1 generation, the analysed characters of two-year old plants differed among the treatments. Sodium azide influenced persimmon stem and leaves in the opposite way, with increase up to 31.57% in plant height and decrease up to 30.33% in leaf petiole length. Changes in morphological characters were significant, that implies the importance of azide influence on the persimmon. Most genotypes treated with 0.1% azide were without significant differences among them and clustered together. The results suggest that the higher azide concentration of 0.5% is more suitable for persimmon seeds azide treatment to form genotypes, significantly different from the control, at the molecular level.

A Critical View on the Phenol Index as a Measure of Phenol Compounds Content in Waters. Application of a Biosensor

Phenol index is considered as an important indicator of water purity and quality. Usually phenol index is determined by a spectrophotometric method the calibration being based on phenol standards. Unfortunately, the absorptivities of different phenols compounds differ from each other. This leads to significant uncertainty concerning content of phenols in water. It is shown that the same shortage of the phenol index appears also if it is determined using an amperometric biosensor based on tyrosinase. The sensitivity of the biosensor response to four phenol compounds: phenol, catechol, 3-cresol and 4-chlorophenol was examined, as well as possible interactions between phenols, according to 24factorial experiment. It was proved that individual phenols affect phenol index independently from each other,ieno significant interaction between phenols was detected. However, sensitivity of the biosensor to different phenols is not the same. Relationship between phenol index and concentrations of phenols in water is discussed.

Distillation Cleanup Preceded GC Determination of Short-Chain Monocarboxylic Acids in Aqueous and Solid Samples of Wastewater Origin

Short-chain monocarboxylic acids (SCMAs) (C2-C5) formed in the process of aerobic biodegradation of larger organic molecules should often be monitored to optimize wastewater biological treatment and study the processes of converting organic waste matter into methane, etc. Gas chromatography (GC) seems a method of choice for such a task. Majority of samples require clean up before they can be injected into GC system. In this work a special refluxing apparatus is applied to concentrate and clean up the troublesome environment samples before injection into GC. To optimize separation of SCMAs in aqueous sample a special arrangement of two capillary columns, of very different polarity was used. The operational parameters of sample preparation were optimized and enrichment factors determined. The procedure developed was applied to determine SCMAs in troublesome aqueous and solid samples of wastewater treatment origin.

Published: July 2012

Restrictions on boys’ capacities to process and to show emotion, however detrimental for their development, constitutes a key lesson of the masculinity curriculum learned in schools. To explore what schools can do to offer support for boys’ resistance to this curriculum, a series of studies has been conducted at a suburban independent school outside Philadelphia, PA. The present study uses a mixed-method design, including teachers, university-based researchers and students on the research team, to examine how boys’ participation in a peer counseling program influenced their sense of self and self-expression. A survey, focus groups, interviews, and observations supported the usefulness of the intervention for boys. The following qualitative themes emerged: (1) The constraining effect of the school’s masculinity culture on boys’ emotional development; (2) the value of a “safe space” in overcoming this culture and in promoting boys’ learning and connection; (3) boys’ ready development of new skills, especially in relation to emotional experiences, when invited to do so; (4) the deepening and broadening of boys’ friendships resulting from their self-disclosure and mutual support.
Results and complications after 2-level axial lumbar interbody fusion with a minimum 2-year follow-up
Authors: Marchi Luis , Oliveira Leonardo , Coutinho Etevaldo , Pimenta Luiz
Published: July 2012

Object

Axial lumbar interbody fusion (AxiaLIF) is a minimally invasive presacral surgical technique that damages neither the anulus fibrosus nor the anterior or posterior longitudinal ligaments. The technique was initially designed and used for L5–S1 interbody fusions and recently was extended to 2-level fusions (L4–5 and L5–S1). Until now, only biomechanical and radiological studies have discussed the feasibility of this new indication, and no clinical study has been published. The purpose of this article is to report results and complications associated with 2-level presacral AxiaLIF with a minimum of 24 months of follow-up.

Methods

In this prospective, nonrandomized, single-center study, 27 patients underwent presacral AxiaLIF surgery at the L4–5 and L5–S1 levels. Clinical outcomes were assessed using the visual analog scale for back and leg symptoms and the Oswestry Disability Index. Radiographic parameters, such as disc height, segmental lordosis, and bone fusion, were analyzed using radiographs and CT scans. Complications and revision surgeries were recorded as needed. The minimum follow-up was 24 months (up to 72 months).

Results

There were no intraoperative complications. One major complication was observed: a patient developed septicemia that resolved after proper care. Clinical outcomes scores showed overall improvement in pain and physical function. During follow-up, the following complications were observed in the construct: screw breakage (14.8%), proximal/distal transsacral rod detachment (11.1%), radiolucency around the transsacral rod (52%), and cephalic rod migration (24%). Disc height gain was reported early after surgery, but at the 24-month follow-up the disc space was diminished in comparison with the preoperative status. Compared with preoperative values, the 24-month results showed loss of segmental lordosis. Only 22% of all treated levels were considered to have solid fusion at the 24-month radiological evaluation.

Conclusions

Patients undergoing presacral 2-level AxiaLIF experienced satisfactory short-term clinical outcomes; however, complications were commonly seen on imaging studies obtained 24 months postoperatively. Additional studies are required to better understand the 2-level indications for this technique.

This paper is concerned with the protection of wind energy systems against the direct effects of lightning. As wind power generation undergoes rapid growth, lightning damages involving wind turbines have come to be regarded as a serious problem. Nevertheless, very few studies exist yet in Portugal regarding lightning protection of wind energy systems using numerical codes. A new case study is presented in this paper, based on a wind turbine with an interconnecting transformer, for the analysis of transient phenomena due to a direct lightning strike to the blade. Comprehensive simulation results are provided by using models of the Restructured Version of the Electro-Magnetic Transients Program (EMTP), and conclusions are duly drawn.

Symmetry-Adapted Fourier Series for the Wallpaper Groups
Authors: Verberck Bart
Published: July 2012

Two-dimensional (2D) functions with wallpaper group symmetry can be written as Fourier series displaying both translational and point-group symmetry. We elaborate the symmetry-adapted Fourier series for each of the 17 wallpaper groups. The symmetry manifests itself through constraints on and relations between the Fourier coefficients. Visualising the equivalencies of Fourier coefficients by means of discrete 2D maps reveals how direct-space symmetry is transformed into coefficient-space symmetry. Explicit expressions are given for the Fourier series and Fourier coefficient maps of both real and complex functions, readily applicable to the description of the properties of 2D materials like graphene or boron-nitride.
Ophthalmological Findings in Congenital Cytomegalovirus Infection: When to Screen, When to Treat?

Published: July 2012

Cytomegalovirus (CMV) is the leading cause of known congenital viral infections. Approximately 90% of congenitally infected newborns exhibit no clinical abnormalities at birth. In 5% to 15%, a wide spectrum of clinical signs is present at birth. Ophthalmological signs are seen in a large percentage of symptomatic patients but rarely in otherwise asymptomatic infants. Chorioretinitis, optic atrophy, and cortical visual impairment are the most frequent causes of visual problems in congenitally infected infants. There is no clear consensus in the literature on screening or treatment modalities concerning the ophthalmological aspects of congenital CMV. Further prospective studies are needed to set up guidelines for ophthalmological screening and treatment of infants with congenital CMV.
Clinical Course and Characteristics of Acute Presentation of Fourth Nerve Paresis
Authors: Khaier Ayman , Dawson Emma , Lee John
Published: July 2012

Purpose:

Many cases of acute-onset cranial nerve paresis have benign etiologies such as microvascular occlusion. Most will resolve completely and neuroimaging is usually unnecessary. Few reports exist on acute fourth nerve paresis.

Methods:

A retrospective review was conducted of all patients presenting with diplopia to the emergency department for 1 year caused by isolated fourth cranial nerve paresis from any cause including trauma.

Results:

Thirty-two patients met the criteria, 26 (81%) males and 6 (19%) females, with an average age of 59.5 years (range: 14 to 80 years). Eighteen (56%) had a microvascular etiology with diabetes mellitus, hypertension, or both; 6 were already taking medication. Six (19%) had decompensating fourth nerve paresis (2 had hypertension and 1 had recent head trauma). Closed head trauma accounted for 2 patients, migraine and herpes zoster virus accounted for one each, and 4 remained unknown. Nineteen patients (59%) were prescribed prisms and 2 patients were given occlusion. Diplopia resolved without treatment in 23 patients (72%) within 2 weeks to 10 months, but 89% of patients with microvascular etiology resolved spontaneously. Three patients continued with prisms, one patient underwent surgery.

Conclusion:

The prognosis for complete and spontaneous resolution of microvascular fourth nerve paresis was excellent, with 89% completely resolved within 10 months.
Contrasting trends in floods for two sub-arctic catchments in northern Sweden – does glacier presence matter?

Published: July 2012

Abstract. Our understanding is limited to how transient changes in glacier response to climate warming will influence the catchment hydrology in the Arctic and Sub-Arctic. This understanding is particularly incomplete for flooding extremes because understanding the frequency of such unusual events requires long records of observation not often available for the Arctic and Sub-Arctic. This study presents a statistical analysis of trends in the magnitude and timing of flood extremes and the mean summer discharge in two sub-arctic catchments, Tarfala and Abisko, in northern Sweden. The catchments have different glacier covers (30% and 1%, respectively). Statistically significant trends (at the 5% level) were identified for both catchments on an annual and on a seasonal scale (3-months averages) using the Mann-Kendall trend test. Stationarity of flood records was tested by analyzing trends in the flood quantiles, using generalized least squares regression. Hydrologic trends were related to observed changes in the precipitation and air temperature, and were correlated with 3-months averaged climate pattern indices (e.g. North Atlantic oscillation). Both catchments showed a statistically significant increase in the annual mean air temperature over the comparison time period of 1985–2009 (Tarfala and Abisko p<0.01), but did not show significant trends in the total precipitation (Tarfala p = 0.91, Abisko p = 0.44). Despite the similar climate evolution over the studied period in the two catchments, data showed contrasting trends in the magnitude and timing of flood peaks and the mean summer discharge. Hydrologic trends indicated an amplification of the streamflow and flood response in the highly glacierized catchment and a dampening of the response in the non-glacierized catchment. The glacierized mountain catchment showed a statistically significant increasing trend in the flood magnitudes (p = 0.04) that is clearly correlated to the occurrence of extreme precipitation events. It also showed a significant increase in mean summer discharge (p = 0.0002), which is significantly correlated to the decrease in glacier mass balance and the increase in air temperature (p = 0.08). Conversely, the non-glacierized catchment showed a significant decrease in the mean summer discharge (p = 0.01), the flood magnitudes (p = 0.07) and an insignificant trend towards earlier flood occurrences (p = 0.53). These trends are explained by a reduction of the winter snow pack due to higher temperatures in the winter and spring and an increasing soil water storage capacity or catchment storage due to progressively thawing permafrost.

Published: July 2012

Purpose

Iron and copper disruption in endometriosis among infertile women has been investigated. Their role in the pathogenesis of endometriosis has also been studied.

Methods

Blood and peritoneal fluid samples were collected from women undergoing laparoscopy. The studied group included 24 infertile women with endometriosis, while 14 women with unexplained infertility represented the control group.

Results

Iron and copper concentrations were estimated. Serum iron levels were significantly lower in infertile endometriotic women compared to the control group. On the other hand, its levels were significantly higher in the peritoneal fluid of infertile endometriotic women than those in controls when they were put side by side. Copper levels were significantly lower in the peritoneal fluid of infertile endometriotic women when measured up to controls. However, there was no significant difference in serum copper levels between the two groups.

Conculsions

Oxidative stress secondary to elevated peritoneal fluid iron, or deficiency of peritoneal copper might play a role in the development and progression of endometriosis, and its related infertility.

The electrochromic and electrocatalytic properties were explored using chronoamperometry (CA), UV/Vis spectroscopy and cyclovoltammetry (CV). The attractable feature is a color change of the film by the reduction of the polyoxometalate at different potentials. The film also exhibits good electrocatalytic activity toward the reduction of IO3

Partenariat, avec ou sans démocratie
Authors: Lapointe Paul-André
Published: July 2012

Cet article traite des rapports entre le partenariat et la démocratie au travail. Sur la base d’une recherche longitudinale effectuée dans six usines de pâtes et papiers au Québec, nous dressons d’abord un portrait des innovations organisationnelles et de la participation syndicale à la gestion. Nous en dégageons différents cas de figure, incarnant la participation et la démocratie à des degrés très variables. La prise en compte de la dynamique des relations entre acteurs sociaux nous permet ensuite de construire une trajectoire de la participation syndicale à la gestion et de mettre en évidence deux configurations opposées au sein du partenariat, se distinguant selon le caractère de la démocratie salariale et l’évolution du pouvoir syndical.
Restructuration industrielle et action syndicale locale
Authors: Bourque Reynald , Rioux Claude
Published: July 2012

La restructuration de l’industrie du papier au Québec a eu un impact majeur sur l’action syndicale. Cet article présente les changements intervenus dans les pratiques syndicales de la Fédération des travailleurs du papier et de la forêt (FTPF-CSN) et de ses syndicats affiliés, notamment en ce qui a trait à la demande de nouveaux services découlant de l’implication syndicale dans la réorganisation du travail. Nous analysons également les effets de ces changements sur les relations entre la FTPF et ses syndicats locaux, ainsi que les problèmes et les défis inhérents au renouvellement des pratiques syndicales.
Connecting Women with Unions
Authors: Forrest Anne
Published: July 2012

This paper investigates the role of “women’s issues” in the decision to join unions by examining a successful organizing drive in a predominantly female workplace. The main focus of the discussion is the identification of women’s issues where they were not immediately apparent to workers and union representatives. The theoretical question raised by this case study is the extent to which women workers’ relationship to unions is similar to or different from men workers’. Contemporary industrial relations discourse tends to emphasize the similarities between women and men, without taking into account well-documented differences in women’s paid and unpaid work and union experiences. From a feminist perspective, the conclusion that gender is unimportant in organizing campaigns often rests on an inadequate analysis of what constitutes women’s workplace/union issues.
Social Investment by Union-Based Pension Funds and Labour-Sponsored Investment Funds in Canada
Authors: Quarter Jack , Carmichael Isla , Sousa Jorge , Elgie Susan
Published: July 2012

This study has two objectives: first, to understand the extent of social investment among union-based pension funds as well as labour-sponsored investment funds in Canada; second, to understand the factors that affect social investment strategies among such funds. A national sample of 189 pension funds with assets of at least $50 million was drawn from the Canadian Pension Fund Investment Directory (Toronto: Maclean Hunter). The sample also included 10 labour-sponsored investment funds, half the number of such funds in Canada. The data indicate that pension funds in Canada have minimal social investment. There is somewhat higher social investment among labour-sponsored investment funds, and particularly labour-sponsored investment funds with genuine union sponsorship. The study also explored factors related to social investment by funds.
Reconnue par l’autre, respectée chez soi : la construction d’un discours politique critique et alternatif par des femmes converties à l’islam en France et au Québec
Authors: Mossière Géraldine
Published: July 2012

Dans les pays occidentaux, le nombre de convertis à l’islam va en augmentant et le phénomène semble toucher davantage les femmes que les hommes. Alors que l’adhésion à l’islam implique l’incorporation d’un nouvel éthos, nous examinons la construction performative du sujet féminin musulman occidental. Les converties interrogées produisent des discours standardisés sur la femme et sur la famille par lesquels elles critiquent les modèles de genre occidentaux et affirment leur appartenance à la communauté musulmane. Tout en reflétant les rapports de pouvoir qui gouvernent les sociétés française et québécoise, les converties formulent des projets politiques qui se posent en alternative aux choix séculier et moderne et contribuent à reconfigurer les domaines du privé et du public, ainsi que les frontières de la marge et du centre. L’article est basé sur un terrain ethnographique comparatif mené auprès de femmes converties en France et au Québec.
Vers une pragmatique de la responsabilité morale
Authors: Métayer Michel
Published: July 2012

La philosophie tente généralement de définir la responsabilité morale dans des termes absolutisants, en prenant soin de se tenir à distance de la réalité empirique du monde social. Cet article présente une approche d'orientation pragmatiste qui plaide en faveur d'un rapprochement entre philosophie et sciences humaines dans l'étude de la responsabilité et qui opère ce rapprochement en se donnant pour objet les « pratiques de responsabilité », plutôt que les critères ou les fondements de la responsabilité. Elle vise à analyser les structures d'interaction à travers lesquelles les agents sociaux s'engagent dans des pratiques concrètes de responsabilisation. Cette approche se veut en prise sur la réalité de l'ordre moral caractéristique des sociétés de la modernité avancée, qu'il faut concevoir comme un système ouvert, mouvant, en perpétuelle reconstruction. C'est un système où les responsabilités ne sont plus attribuées sur un mode autoritaire, dans des cadres rigides et suivant des critères prédéfinis et stables, mais sont largement abandonnées à l'initiative des acteurs sociaux.
Une histoire sans fin : l'implantation des services de garde pour enfants au Canada durant les années 1970
Authors: Mahon Rianne
Published: July 2012

En raison de la présence croissante des femmes sur le marché du travail depuis quelques décennies, on presse les gouvernements de participer à l'organisation de services de garde pour enfants. Dans certains pays toutefois, et le Canada est du nombre, les positions contradictoires des acteurs impliqués font de la lutte pour la mise en place de services universels une « histoire sans fin ». Dans l'épisode présenté ici, on voit comment, après les travaux de la Commission royale d'enquête sur la situation de la femme au Canada, les féministes ont vainement tenté de faire échec à la logique assistancielle qui, déjà, avait engendré des mesures ciblées sur les pauvres et les clientèles « à risque ». Néanmoins, au sein de la bureaucratie fédérale, un premier noyau de « féministes d'État » a combattu pour élargir l'accès de ces services aux classes moyennes.
La transformation des obligations de travail pour les mères touchant l'assistance sociale : quels enseignements tirer pour les féministes ?
Authors: Morel Sylvie
Published: July 2012

La configuration des droits et des devoirs de l'institution de l'assistance sociale est fortement imprégnée d'une logique de genre. À partir de l'analyse évolutionnaire des obligations de travail imposées aux mères pauvres recevant des transferts assistanciels, nous procédons à une lecture critique d'une stratégie féministe qui vise la reconnaissance du travail des femmes dans la famille par la consolidation de l'assistance sociale. Avec la transformation de l'institution de l'emploi des femmes, les risques d'une telle stratégie sont suffisamment importants pour forcer les féministes à engager une réflexion fondamentale au sujet des politiques de sécurité sociale à promouvoir pour améliorer véritablement le statut économique des femmes.
Entre la oumma, l’ethnicité et la culture : le rapport à l’islam chez les musulmans francophones de Montréal
Authors: Fortin Sylvie , LeBlanc Marie Nathalie , Le Gall Josiane
Published: July 2012

Au Québec, la migration croissante de musulmans donne à voir un islam pluriel. Néanmoins, depuis septembre 2001, la question identitaire se pose avec plus d’acuité pour les musulmans d’Amérique du Nord. Ce contexte couplé au maintien quotidien de liens hors du territoire local et à l’avènement de nouveaux acteurs internationaux favorisent un sentiment d’appartenir à uneoummauniverselle, appartenance non pour autant détachée d’un rapport au territoire local ou d’origine. À partir d’une recherche sur les pratiques sociales et rituelles de musulmans Libanais, Ouest-Africains et Maghrébins de Montréal, nous argumentons que la sociabilité de ces populations s’articule entre religion, ethnicité et culture. En examinant les pratiques communautaires ainsi que les dynamiques de transmission identitaire aux enfants et de définition des frontières symboliques des groupes, nous exposons la diversité des stratégies identitaires et réfutons la présence d’un islam essentialisé en contexte montréalais.
Effect of different salts on the development of Fusarium solani var. coeruleum, a causal agent of potato dry rot
Authors: Mecteau Mélanie R. , Arul Joseph , Tweddell Russell J.
Published: July 2012

The objectives of this study were (1) to evaluate the effect of different salts on the in vitro development of Fusarium solani var. coeruleum, and (2) to evaluate the efficacy of the salts for reducing dry rot severity caused by the pathogen in potato tubers. The study showed that several salts significantly inhibited the mycelial growth of F. solani var. coeruleum. Aluminium acetate, aluminium chloride, sodium benzoate, sodium metabisulfite, potassium sorbate and trisodium phosphate completely inhibited mycelial growth. Exposure of F. solani var. coeruleum conidia to aluminium acetate, potassium sorbate, sodium benzoate, sodium metabisulfite or trisodium phosphate at 0.2 M resulted in 100% mortality of the conidia after 1 h while aluminium chloride and aluminium lactate caused 100% mortality after an exposure of 24 h. In order to evaluate the effect of salts on potato dry rot development, F. solani var. coeruleum-inoculated tubers were treated with the different salts and disease severity was evaluated following an incubation period of 7 d. Among the test salts, only aluminium chloride caused a significant reduction in potato dry rot compared with the control. The study points out the possibility of using aluminium chloride to control potato dry rot.
Les obstacles à la mixité dans la gestion par projets
Authors: Legault Marie-Josée , Chasserio Stéphanie
Published: July 2012

Il y a peu de femmes chez les professionnels qualifiés des services technologiques aux entreprises, métiers de l’informatique, en Europe comme en Amérique. Le mode d’organisation du travail qu’on y pratique est celui de la gestion par projets, qui a de multiples conséquences en termes de conditions de travail : l’importance des longues heures et la résistance à la réduction du temps de travail, les heures supplémentaires non payées, la très grande flexibilité exigée des employés, les aménagements d’heure ou de lieu de travail sujets à négociation avec le chef de projet, selon des critères arbitraires. Les femmes sont celles que défavorise un tel système, car on observe un lien entre la flexibilité à cet égard et le fait d’avoir la responsabilité principale des enfants.
La validation des acquis de l’expérience (VAE) : entre gestion individuelle et organisationnelle des carrières
Authors: Ballet Valérie
Published: July 2012

La gestion des carrières, quelle soit individuelle ou organisationnelle, est devenue un enjeu majeur dans la société actuelle. En France, cette problématique est promue dans le cadre d’une Loi spécifique, mais elle est aussi complétée et associée largement à la logique compétences, reconnaissance des acquis et formation tout au long de la vie. Dans ce cadre particulier, la Loi de Modernisation Sociale développe la démarche de validation des acquis de l’expérience. Cette validation des acquis de l’expérience vient renforcer et innover dans les pratiques de gestion des carrières. À titre individuel, la validation des acquis de l’expérience s’inscrit dans un projet professionnel et personnel particulier, propre à une gestion singulière. À titre organisationnel, elle accroît les possibilités de gestion des carrières des salariés en se centrant sur des axes de gestion des ressources humaines variées. De ce fait, la validation des acquis de l’expérience contribue à la gestion des carrières.
