Présentation de l'adaptation française de « l'échelle de coparentage » de McHale pour familles avec jeunes enfants [Presentation of the french adaptation of McHale's coparenting scale for families with young children.]

The aim of this paper is to present McHale's coparenting scale,a self-administered questionnaire enabling assessment of the quality of coparenting, and first steps in structural and construct validation of the French version. A total of 41 French speaking Swiss families and 84 US families completed this questionnaire and the Dyadic Adjustment Scale, a measure of marital satisfaction. The results of the Swiss families correspond to those of US families: first, items distributed into four factors (family integrity, conflict, affection and disparagement) and second, a partial link was found between quality of coparenting and marital adjustment. This finding supports the construct validity of the questionnaire, reflecting the established link between these two family sub-systems. Given that coparenting quality has a major influence on children's socio-affective development, the questionnaire will find great use in assessing not just negative features of coparenting, such as conflicts and disparagement, but also positive components such as warmth and support. This will be an important asset for research as well as clinical purposes.

Marginal adaptation in vitro and clinical outcome of Class V restorations

OBJECTIVES: We examined the correlation between the quantitative margin analysis of two laboratory test methods (Berlin, Zurich) and the clinical outcome in Class V restorations. METHODS: Prospective clinical studies with an observation period of at least 18 months were searched in the literature, for which laboratory data were also available. The clinical outcome variables were retention loss, marginal discoloration, detectable margins and secondary caries. Forty-four clinical studies matched the inclusion criteria, including 34 adhesive systems for which laboratory data were also present. For both laboratory test methods and the clinical studies, an index was formulated to better compare the in vitro and in vivo results. Linear mixed models which included a random study effect were calculated. As most clinical data were available for 12 and 24 months, the main analysis was restricted to these recall intervals. RESULTS: The comparative analysis revealed a weak correlation between the clinical index and both in vitro indices. The correlation was statistically significant for the Berlin method but not for the Zurich method and only present if studies were compared which used the same composite in the in vitro and in vivo study. When defining specific cut-off values, the prognosis for the good clinical performance of an adhesive system based on in vitro results was 78% (Berlin) or 100% (Zurich). For poor performance it was 67% and 60%, respectively. No correlation was found between both in vitro methods. SIGNIFICANCE: The surrogate parameter "marginal adaptation" of restorations placed in extracted teeth has a mediocre value to predict the clinical performance of an adhesive system in cervical cavities. The composite is an important factor for a successful prediction. The comparison between in vitro/in vivo is sometimes hampered by the great variability of clinical results on the same adhesive system.

Stress Perception in Public Organizations: Expanding the Job Demands - Job Resources Model by Including Public Service Motivation

Although stress has been a longstanding issue in organizations and management studies, it has never been studied in relation to Public Service Motivation. This article therefore aims to integrate PSM into the job demands-job resources model of stress in order to determine whether PSM might contribute to stress in public organizations. Drawing upon original data from a questionnaire in a Swiss municipality, this study unsurprisingly shows that "red tape" is an antecedent of stress perception, whereas satisfaction with organizational support, positive feedback, and recognition significantly decrease the level of perceived stress. Astonishingly, the empirical results show that PSM is positively and significantly related to stress perception. By increasing individuals' expectations towards their jobs, PSM might thus contribute to increased pressure on public agents. Ultimately, this article investigates the "dark side" of PSM, which has been neglected by the literature thus far.

THE HIGH DIAGNOSTIC YIELD OF A GERIATRIC OUTPATIENT CLINIC

Objectives: To determine characteristics of older patients referred to a geriatric outpatient clinic; 2) to determine the prevalence of geriatric syndromes in this population; 3) to identify main recommendations made to referring primary care physicians. Design: Cross-sectional analysis Setting: Outpatient clinic of the service of geriatric medicine at the University of Lausanne Medical Center, Lausanne, Switzerland. Participants: Community-dwelling patients aged 65 and over referred to the clinic. Measurements: Demographics, social, functional and health status data, main diagnoses identified and recommendations made for primary care physicians were collected prospectively. Results: Subjects (N=206, mean age 79.7±7.6 years, 57.3% women, 48.5% living alone, 36.9% receiving formal home care) were referred by primary care physicians (76%), hospitalists (18%), or family members (7%). Main reasons for referral were request for comprehensive assessment, cognitive evaluation, and mobility assessment (45.2%, 26.2%, and 15.5%, respectively). 21.4% of patients are independent in Lawton's Instrumental ADL and 47.1% are independent in Katz's Basic ADL, and 57.3% of patients reported having fallen once or more over the last year. Overall, 76.2% of patients had gait and balance impairment, 72.8% cognitive impairment, 57.3% polypharmacy (≥6 drugs; median 6.5±3.9, IQR 4-8), 54.4% affective disorder, 48.3% osteoporosis, 45.1% urinary incontinence and 33.8% orthostatic hypotension. Polymorbidity (≥6 geriatric syndromes) was present in 58.3% of referred patients. On average, patients received 10.6±4.0 recommendations, including fall prevention interventions (85.2 % of patients: walking aid adaptation in 48.1%, vitamin D prescription in 59.7%, home hazards assessment in 59.2%, and exercise prescription in 53.4%), referral to a memory clinic (45.6%), and treatment modifications (69.9 % of all patients and 81.6% of patients with polypharmacy, mostly psychotropic drugs discontinuation). Conclusions: Polymorbidity was frequent in these older outpatients, with polypharmacy, mobility and cognitive impairments being most prevalent. Outpatient geriatric consultation is a good opportunity to identify geriatric syndromes and propose interventions to prevent or delay functional decline.

Suivi du patient après transplantation cardiaque: monitoring et adaptation de l'immunosuppression [Monitoring and adjustment of immunosuppression after heart transplantation].

Heart transplantation remains the best therapeutic option for the treatment of end-stage heart failure. However, good survival rates can be obtained only if patients are closely monitored, particularly for their immunosuppressive regimens. Currently, a triple-drug regimen usually based on calcineurin-inhibitors (cyclosporin A or tacrolimus), anti-proliferative agents and steroids is used in most recipients. New agents such as the mTOR inhibitors, a more recently developed class of immunosuppressive drugs, can also be used in some patients. The aim of this article is to review currently used immunosuppressive regimens after heart transplantation, and to propose some individualized options depending on specific patient characteristics and recent pharmacological developments in the field.

Adaptation to larval malnutrition does not affect fluctuating asymmetry in Drosophila melanogaster

Both stress during development and response to directional selection were proposed to lead to reduced developmental stability of an organism, commonly measured as fluctuating asymmetry. Here, we investigated the direct physiological (plastic) effect of larval malnutrition and the effect of evolutionary adaptation to this form of stress on developmental stability, measured as fluctuating asymmetry of several wing measurements. The measurements were made on female Drosophila melanogaster from populations which, in the course of 84 generations of experimental evolution, adapted to malnutrition and from non-adapted controls, raised either under standard conditions or under nutritional stress. We detected no changes in the levels of fluctuating asymmetry as either a plastic or an evolutionary response. Thus, neither nutritional stress within lifetime nor directional selection it imposes seems to affect developmental stability in flies.

Natural Arabidopsis brx loss-of-function alleles confer root adaptation to acidic soil.

Soil acidification is a major agricultural problem that negatively affects crop yield. Root systems counteract detrimental passive proton influx from acidic soil through increased proton pumping into the apoplast, which is presumably also required for cell elongation and stimulated by auxin. Here, we found an unexpected impact of extracellular pH on auxin activity and cell proliferation rate in the root meristem of two Arabidopsis mutants with impaired auxin perception, axr3 and brx. Surprisingly, neutral to slightly alkaline media rescued their severely reduced root (meristem) growth by stimulating auxin signaling, independent of auxin uptake. The finding that proton pumps are hyperactive in brx roots could explain this phenomenon and is consistent with more robust growth and increased fitness of brx mutants on overly acidic media or soil. Interestingly, the original brx allele was isolated from a natural stock center accession collected from acidic soil. Our discovery of a novel brx allele in accessions recently collected from another acidic sampling site demonstrates the existence of independently maintained brx loss-of-function alleles in nature and supports the notion that they are advantageous in acidic soil pH conditions, a finding that might be exploited for crop breeding.

L'intégration de l'adaptation au changement climatique dans la conduite des politiques publiques: déficit de mise en oeuvre ou déficit de légitimité?

L'échec des tentatives de juguler les émissions globales de gaz à effet de serre a mené au renforcement d'un discours sur la nécessité de l'adaptation au changement climatique. Il est de plus souvent considéré qu'une transformation de l'action publique serait nécessaire afin de réduire les impacts de grande magnitude qui découlent du changement climatique. Depuis les années 2000, on constate ainsi un développement des activités étatiques dans le domaine de l'adaptation. Cette évolution suscite une question centrale: quels sont les effets réels que provoque l'intégration de l'adaptation au changement climatique dans la conduite des politiques publiques et comment expliquer les éventuelles limites à ces processus? La littérature spécialisée sur l'adaptation fait preuve d'un certain réductionnisme à l'égard de la complexité de l'action publique en considérant que lorsque la capacité d'agir contre le problème de la vulnérabilité au changement climatique existe, toute forme d'inaction publique serait un déficit de mise en oeuvre provoqué par des barrières à l'action qu'il faudrait lever. A contrario, cette thèse considère l'adaptation comme une norme de politique publique dont l'intégration est susceptible de provoquer des changements institutionnels dans la forme et le contenu des politiques publiques, et des effets concrets sur les acteurs vulnérables au changement climatique. Afin de mesurer les effets de l'intégration politique de l'adaptation, un concept est formulé sur la base d'un idéal-type du régime institutionnel adaptatif, soit une construction théorique des régulations qu'impliquerait une gestion cohérente du système socioécologique complexe dans lequel s'insère le système climatique. L'auteur propose un cadre d'analyse empirique des processus publics d'adaptation qu'il applique ensuite à deux États: l'Inde (politique agricole) et la Suisse (politique du tourisme hivernal), avec pour objectif de repérer des mécanismes explicatifs communs aux effets de l'intégration dans ces deux contextes extrêmement dissemblables. L'étude débouche sur six résultats qui constituent une contribution appréciable à la littérature. L'auteur montre: premièrement, que l'intégration politique de l'adaptation conduit à une production d'actes symboliques, qui s'explique notamment par le manque de pression publique à agir sur le problème de la vulnérabilité au changement climatique; deuxièmement, que le processus d'intégration agit sur la réalité sociale par le biais d'un mécanisme d'attribution de ressources publiques à certains acteurs du champ politique; troisièmement, que les groupes sociaux qui bénéficient de ces ressources publiques ne sont pas nécessairement les plus vulnérables, mais ceux détenant les ressources d'action nécessaires à l'activation de l'intervention publique; quatrièmement, que l'absence de clefs de répartition des coûts de l'adaptation, de procédures de monitoring et d'instruments d'action contraignants limitent les effets des programmes publics d'adaptation; cinquièmement, que la faible articulation institutionnelle entre objectif d'adaptation et objectifs de protection de l'environnement accentue le risque de processus d'adaptation produisant des externalités environnementales; sixièmement, que les transformations dont la littérature souligne la nécessité ne sont pas nécessairement faisables ni désirables. Sur la base de cette analyse, cette thèse s'écarte de la littérature dominante en concluant que les processus publics d'adaptation ne souffrent pas d'un déficit de mise en oeuvre, mais d'un déficit de légitimité lié à leurs effets pernicieux. L'auteur formule alors trois recommandations pour améliorer la légitimité de ces politiques et trois questions ouvertes sur le futur politique de l'adaptation.

Forensic examination of ink by high-performance thin layer chromatography - The United States Secret Service Digital Ink Library

Forensic examinations of ink have been performed since the beginning of the 20th century. Since the 1960s, the International Ink Library, maintained by the United States Secret Service, has supported those analyses. Until 2009, the search and identification of inks were essentially performed manually. This paper describes the results of a project designed to improve ink samples' analytical and search processes. The project focused on the development of improved standardization procedures to ensure the best possible reproducibility between analyses run on different HPTLC plates. The successful implementation of this new calibration method enabled the development of mathematical algorithms and of a software package to complement the existing ink library.
