Psychometric Properties of the German Version of the Barratt Impulsiveness Scale, Version 11 (Bis–11) for Adolescents
Authors: Hartmann Andrea S. , Rief Winfried , Hilbert Anja
Published: May 2011

Impulsiveness is increasingly gaining attention as a potential risk factor for various mental disorders. Until now, there have been German instruments that allowed for assessing adolescents' self-reported impulsiveness multi-dimensionally. The present study examined the German version of the Barratt Impulsiveness Scale–11 (BIS–11) for adolescents. The instrument was completed by 659 adolescents ages 10 to 20 years; 98 were retested after 6 months. Items showed adequate psychometric properties. An exploratory factor analysis identified three factors that showed slight differences from the initial questionnaire proposed by Barratt. The factors showed low to moderate intercorrelations, satisfactory internal consistency (dependent on factor), and were stable over time. Convergent validity was ascertained, and the item pool showed sufficient power to discriminate adolescents with symptoms of attention deficit hyperactivity disorder and those with loss of eating control from healthy adolescents. Findings suggest that the German BIS–11 is appropriate for reliable investigation of impulsiveness in adolescents. Future research should examine sensitivity as a screening tool, as well as sensitivity to change.
Factor Structure of the Spanish Version of the Object-Spatial Imagery and Verbal Questionnaire
Authors: Campos Alfredo , Pérez-Fabello María José
Published: May 2011

The reliability and factor structure of the Spanish version of the Object-Spatial Imagery and Verbal Questionnaire (OSIVQ) were assessed in a sample of 213 Spanish university graduates. The questionnaire measures three types of processing preferences (verbal, object imagery, and spatial imagery). Principal components analysis with varimax rotation identified three factors, corresponding to the three scales proposed in the original version, explaining 33.1% of the overall variance. Cronbach's alphas were .72, .77, and .81 for the verbal, object imagery, and spatial imagery scales, respectively.

Authors: Vázquez Fernando L. , Otero Patricia , Díaz Olga , Sánchez Teresa , Pomar Carmen
Published: May 2011

The emotional intelligence of a sample of 59 women caregivers ( M age = 51.1 yr.) with depressive symptoms was compared with that of a sample of adult women from the general population ( M age = 50.7 yr.). No group differences were observed on the Trait Meta-Mood Scale's three dimensions of emotional intelligence across age, socioeconomic status, or education level. Compared with the general population sample, the caregivers group scored significantly lower on Attention to Feelings and Mood Repair.

Published: May 2011

Using a sample of 647 Canadian children in kindergarten to Grade 3 (325 boys, 322 girls), the present study evaluated the perceived effectiveness of Skillstreaming (McGinnis & Goldstein, 2003), a widely known social skills program implemented to target the development of four skill sets, i.e., listening, following directions, problem-solving, and knowing when to tell. Results indicated significant postprogram improvements in all skills as well as in ratings of overall pro-sociality obtained from both classroom teachers and mental health staff, with medium to large effect sizes obtained from teachers' and mental health professionals' ratings, respectively. Additional analyses yielded significant but weak moderator effects of grade and preprogram prosocial functioning for teacher ratings but no consistent moderator effects for children's sex or school location (i.e., urban versus rural) regardless of rater.
Developmental Trajectories of Marijuana Use from Adolescence to Adulthood: Personality and Social Role Outcomes
Authors: Brook Judith S. , Lee Jung Yeon , Brown Elaine N. , Finch Stephen J. , Brook David W.
Published: May 2011

Longitudinal trajectories of marijuana use from adolescence into adulthood were examined for adverse life-course outcomes among African-Americans and Puerto Ricans. Data for marijuana use were analyzed at four points in time and on participants' personality attributes, work functioning, and partner relations in adulthood using growth mixture modeling. Each of the three marijuana-use trajectory groups (maturing-out, late-onset, and chronic marijuana-users) had greater adverse life-course outcomes than a nonuse or low-use trajectory group. The chronic marijuana-use trajectory group was highly associated with criminal behavior and partners' marijuana use in adulthood. Treatment programs for marijuana use should also directly address common adverse life-course outcomes users may already be experiencing.
Dyslexia and Handedness: Developmental Phonological and Surface Dyslexias are Associated with Different Biases for Handedness
Authors: Annett Marian
Published: May 2011

Developmental disorders of reading and spelling have long been associated with increased left- and mixed-handedness but the evidence has been controversial. The right shift (RS) theory of handedness and cerebral dominance, developed by Annett from 1972 onward, offers resolutions to several puzzles about laterality in the so-called dyslexias. This review of findings in the light of the theory shows that “phonological” dyslexies are less likely to be right-handed, while “surface” or “dyseidetic” dyslexies are more likely to be right-handed than the general population.
Effects of Interior Colors on Mood and Preference: Comparisons of Two Living Rooms
Authors: Yildirim Kemal , Hidayetoglu M. Lutfi , Capanoglu Aysen
Published: May 2011

The purpose was to assess whether various colors across room interiors do, in fact, evoke different moods. Digital images of two imaginary living rooms were used as the experimental settings. For each of the experiments, the rooms' spatial characteristics were fixed, with only the colors changed: either warm, cool, or achromatic colors. As predicted, warm colors tended to produce stronger participant responses when rating the scene on “high arousal,” “exciting,” and “stimulating.” Cool colors tended be associated with “not very arousing,” but to be rated higher on “spacious” and “restful.” It is generally assumed that cool and achromatic colors evoke calmer and more peaceful emotions. The study's results show that the spatial characteristics of the imaginary spaces themselves affected participants' responses only on measures of “happiness” and “vividness.” Lastly, sex differences were also found, with women's ratings generally more positive than those of men.
Challenging an Authorial Attribution: Vocabulary and Emotion in a Translation of Goethe's Faust Attributed to Samuel Taylor Coleridge
Authors: Whissell Cynthia
Published: May 2011

This article disputes the stylometric attribution of an anonymous English 1821 translation of Goethe's German verse drama Faust to the poet and critic Samuel Taylor Coleridge. The translation was compared to four known Coleridgean dramas, two of which were translations from German. Evidence challenging Coleridge's authorship came from words used proportionally more often by Coleridge, words used proportionally more often by the unknown translator, differential employment of parallel word forms (“O” and “hath” for Coleridge, “oh” and “has” for the translator), and differences in the undertones of the two vocabularies, as measured by the Dictionary of Affect in Language (Coleridge's undertones were less pleasant and more abstract). Some problems with the stylometry of the challenged attribution to Coleridge are noted.
Neoadjuvant Therapy in Patients with Pancreatic Cancer: A Disappointing Therapeutic Approach?
Authors: Zimmermann Carolin , Folprecht Gunnar , Zips Daniel , Pilarsky Christian , Saeger Hans Detlev , Grutzmann Robert
Published: May 2011

Pancreatic cancer is a devastating disease. It is the fourth leading cause of cancer-related death in Germany. The incidence in 2003/2004 was 16 cases per 100.000 inhabitants. Of all carcinomas, pancreatic cancer has the highest mortality rate, with one- and five-year survival rates of 25% and less than 5%, respectively, regardless of the stage at diagnosis. These low survival rates demonstrate the poor prognosis of this carcinoma. Previous therapeutic approaches including surgical resection combined with adjuvant therapy or palliative chemoradiation have not achieved satisfactory results with respect to overall survival. Therefore, it is necessary to evaluate new therapeutic approaches. Neoadjuvant therapy is an interesting therapeutic option for patients with pancreatic cancer. For selected patients with borderline or unresectable disease, neoadjuvant therapy offers the potential for tumor downstaging, increasing the probability of a margin-negative resection and decreasing the occurrence of lymph node metastasis. Currently, there is no universally accepted approach for treating patients with pancreatic cancer in the neoadjuvant setting. In this review, the most common neoadjuvant strategies will be described, compared and discussed.
Welcome to Catalysts––A New Open Access Journal for a Growing Scientific Community

Published: May 2011

There is something intrinsically fascinating about catalysts. The thought that a material can speed up a reaction by hundreds or thousands of times without being consumed is truly amazing. I frequently have the pleasure of teaching undergraduate and graduate chemical reaction engineering courses that include sections on catalysts. I have found that students take an immediate interest in catalysts and are fascinated by how they work. I certainly have been captivated with catalysts myself, as I have devoted my entire academic career to studying their properties. [...]
First-Principles Investigation of Ag-Doped Gold Nanoclusters

Published: May 2011

Gold nanoclusters have the tunable optical absorption property, and are promising for cancer cell imaging, photothermal therapy and radiotherapy. First-principle is a very powerful tool for design of novel materials. In the present work, structural properties, band gap engineering and tunable optical properties of Ag-doped gold clusters have been calculated using density functional theory. The electronic structure of a stable Au20 cluster can be modulated by incorporating Ag, and the HOMO–LUMO gap of Au20−nAgn clusters is modulated due to the incorporation of Ag electronic states in the HOMO and LUMO. Furthermore, the results of the imaginary part of the dielectric function indicate that the optical transition of gold clusters is concentration-dependent and the optical transition between HOMO and LUMO shifts to the low energy range as the Ag atom increases. These calculated results are helpful for the design of gold cluster-based biomaterials, and will be of interest in the fields of radiation medicine, biophysics and nanoscience.

Authors: Booth Leigh , Catledge Shane A. , Nolen Dustin , Thompson Raymond G. , Vohra Yogesh K.
Published: May 2011

With incredible hardness and excellent wear-resistance, nanocrystalline diamond (NCD) coatings are gaining interest in the biomedical community as articulating surfaces of structural implant devices. The focus of this study was to deposit multilayered diamond coatings of alternating NCD and microcrystalline diamond (MCD) layers on Ti-6Al-4V alloy surfaces using microwave plasma chemical vapor deposition (MPCVD) and validate the multilayer coating’s effect on toughness and adhesion. Multilayer samples were designed with varying NCD to MCD thickness ratios and layer numbers. The surface morphology and structural characteristics of the coatings were studied with X-ray diffraction (XRD), Raman spectroscopy, and atomic force microscopy (AFM). Coating adhesion was assessed by Rockwell indentation and progressive load scratch adhesion tests. Multilayered coatings shown to exhibit the greatest adhesion, comparable to single-layered NCD coatings, were the multilayer samples having the lowest average grain sizes and the highest titanium carbide to diamond ratios.

Published: May 2011

Gaultheria yunnanensis (Franch.) Rehder is a kind of traditional Chinese herbal medicine used for the treatments of rheumatoid arthritis, swelling and pain. Two methyl salicylate glycosides, namely methyl benzoate-2-O-b-D-xylopyranosyl(1-6)-O-b-D-gluco-pyranoside (J12122) and methyl benzoate-2-O-β-D-xylopyranosyl(1-2)[O-β-D-xylopyranosyl(1-6)]-O-β-D-glucopyranoside (J12123), are natural salicylic derivatives isolated from Gaultheria yunnanensis. In this study, we investigated the anti-inflammatory activity of J12122 and J12123 on LPS-induced RAW264.7 macrophage cells by measuring the production of pro-inflammatory cytokines, accumulation of nitric oxide (NO), and level of reactive oxygen species (ROS). The results showed that both methyl salicylate glycosides dose-dependently inhibited the production of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6, respectively. Consistent with these observations, J12122 and J12123 significantly suppressed the accumulation of NO, with an inhibitory rate of 56.20% and 51.72% at 3.0 μg/mL concentration, respectively. Furthermore, the two methyl salicylate glycosides reduced the level of ROS induced by LPS. These results showed that the isolated compounds possess anti-inflammatory properties through inhibition the production pro-inflammatory cytokines, NO, and ROS.

Authors: Cotoras Milena , Mendoza Leonora , Muñoz Alexis , Yáñez Karen , Castro Paulo , Aguirre María
Published: May 2011

The fungotoxicity against Botrytis cinerea of a flavonoid isolated from Pseudognaphalium robustum was analyzed. Two absorption column chromatographies and one semipreparative thin layer chromatography were used to purify the active flavonoid. It was determined, by 1H-NMR spectroscopy and co-elution with standards in HPLC, that this compound was 5,7-dihydroxy-3,8-dimethoxyflavone (gnaphaliin A). To determine the fungitoxicity of the purified compound, the effect on in vitro mycelial growth and conidial germination was studied. The compound concentration that reduced mycelial growth by 50% was 45.5 mg/mL. This compound also partially affected conidial germination of B. cinerea, reduced oxygen consumption by germinating conidia and affected the integrity of plasma membrane. Finally, using cyclic voltammetry, it was shown that the purified flavone had a pro-oxidant effect.
Protein Biosensors Based on Polymer Nanowires, Carbon Nanotubes and Zinc Oxide Nanorods
Authors: Kumar M. Anish , Jung Soyoun , Ji Taeksoo
Published: May 2011

The development of biosensors using electrochemical methods is a promising application in the field of biotechnology. High sensitivity sensors for the bio-detection of proteins have been developed using several kinds of nanomaterials. The performance of the sensors depends on the type of nanostructures with which the biomaterials interact. One dimensional (1-D) structures such as nanowires, nanotubes and nanorods are proven to have high potential for bio-applications. In this paper we review these three different kinds of nanostructures that have attracted much attention at recent times with their great performance as biosensors. Materials such as polymers, carbon and zinc oxide have been widely used for the fabrication of nanostructures because of their enhanced performance in terms of sensitivity, biocompatibility, and ease of preparation. Thus we consider polymer nanowires, carbon nanotubes and zinc oxide nanorods for discussion in this paper. We consider three stages in the development of biosensors: (a) fabrication of biomaterials into nanostructures, (b) alignment of the nanostructures and (c) immobilization of proteins. Two different methods by which the biosensors can be developed at each stage for all the three nanostructures are examined. Finally, we conclude by mentioning some of the major challenges faced by many researchers who seek to fabricate biosensors for real time applications.
Accumulation Kinetics of Three Scirpentriol-Based Toxins in Oats Inoculated in Vitro with Isolates of Fusarium sporotrichioides and Fusarium poae

Published: May 2011

Autoclaved oats were inoculated with a strain of Fusarium sporotrichioides or Fusarium poae. Moisture content of oats after inoculation was at 38%, incubation took place in standing culture at 28 °C. The A-type trichothecenes, 4,15-diacetoxyscirpenol (4,15-DAS), 15-monoacetoxyscirpenol (15-MAS), and scirpentriol (SCIRP) were analyzed by GC/MS. For each strain, three culture flasks were harvested at 2–3 day intervals starting immediately after inoculation. Total incubation time was 42 days (F. poae) and 56 days (F. sporotrichioides). Following peak accumulation, 4,15-DAS decreased below the detection limit for both strains, 15-MAS decreased below this limit for the isolate of F. sporotrichioides, for the isolate of F. poae it decreased to a level markedly below the peak value. SCIRP, after having peaked, decreased to some extent for the strain F. sporotrichioides, with a significant (P = 0.0029) negative linear regression of toxin content against culture age during this period. The content of 15-MAS, and in part also of 4,15-DAS, decreased along with an increase of SCIRP. This sequential accumulation pattern suggests the successive induction of esterases deacetylating 4,15-DAS and 15-MAS, as well as of enzymes involved in the metabolization of the parent alcohol, SCIRP. The results may explain, at least in part, the somewhat higher incidence in naturally contaminated compounds reported in the literature for SCIRP compared to 4,15-DAS and 15-MAS.
Emploi des seniors : bilan et perspectives

Senior Employment: Overview and Prospects

This article provides an overview of the evolution of the senior workforce in France since 1975 by investigating the main determinants of employment for 50 to 64-year olds. The mid-1990s is found to be a turning point during which the increasing concentration of economic activity on middle-aged workers (30-49) came to a halt and the declining employment share of senior workers stabilized at its lowest level. However, in 2005, the employment rate for over 60-year olds in France was still the lowest in the EU-25. While the productivity of seniors does not seem to play a significant role, the behaviors and attitudes formed after thirty years of access to pre-retirement plans most likely have contributed to the low employment share of seniors in the labor market. International comparisons, however, call for a better understanding of income patterns at the very end of careers. This retrospective look at the senior workforce over the past thirty years suggests that keeping older workers in the labour market, as is the goal of retirement benefit reform, will be more costly if pre-retirement plans result in the production process being made irrevocable unfavorable for senior workers.
L'uniformité versus la différenciation des normes dans les accords environnementaux internationaux
Authors: Bayramoglu Basak
Published: May 2011

Les accords environnementaux internationaux sont caractérisés par des objectifs de dépollution soit uniformes soit différenciés pour des pays. L'efficacité économique requiert, a priori, la mise en place des règles de réduction différenciées selon les pays. Or, on observe que la plupart des accords environnementaux signés actuellement au niveau international sont régis par des règles uniformes de réduction des émissions. Des arguments théoriques, comme l'existence du commerce international entre pays ou la difficulté d'aboutir à un accord, peuvent expliquer l'usage de ces règles. L'objectif de ce travail est de préciser les contours factuels et théoriques de l'utilisation fréquente des règles uniformes dans ces accords. Après une description de la nature des accords environnementaux internationaux, nous analysons les règles de réduction des émissions actuellement utilisées dans les négociations internationales pour l'environnement. Cette analyse est mise en perspective avec l'étude des normes pour la régulation des problèmes de pollution domestique pour laquelle le clivage entre les normes uniformes et les normes différenciées existe également. La dernière section fournit une revue de la littérature théorique sur l'évaluation de l'efficacité économique et environnementale des normes uniformes dans les accords environnementaux internationaux.
Comment faut-il distribuer les quotas échangeables de gaz à effet de serre ?
Authors: Quirion Philippe
Published: May 2011

How Should Greenhouse Gas Tra- dable Allowances be Allocated?

The current revision of the European Union greenhouse gas emission trading system, in place since 2005, should modify the way allowances are distributed. We compare two distribution methods: a lump-sum allocation, based solely on past information, and an allocation porportional to the current output level. We identify the pros and cons of each allocation method and conclude that it is essential to distinguish the sectors sheltered from international competition, like power generation, from the exposed sectors. In the sheltered sectors, the allocation proportional to the current output level entails a much higher cost, and lump-sum allocation is unfair. Hence we favour auctioning, which does not suffer from these drawbacks. However, in exposed sectors, the allocation proportional to the current output level is an option worth considering.
Salaires et carrières dans la fonction publique - le cas des éboueurs
Authors: Jaaidane Touria , Gary-Bobo Robert
Published: May 2011

En nous appuyant sur une reconstruction des grilles indiciaires des fonctionnaires territoriaux, qui s'appliquent aux éboueurs et chefs d'équipe du nettoiement, échelon par échelon, de 1977 à 2004, nous montrons que les rémunérations brutes réelles des éboueurs de la mairie de Paris ont été rattrapées par le smic, pendant que la politique d'externalisation des services de nettoiement conduisait à une baisse des effectifs d' éboueurs fonctionnaires et à une très nette réduction de l'incidence des grèves. En prenant pour chaque année la règle d'avancement en vigueur, nous calculons la valeur actualisée espérée réelle des rémunérations d'un agent qui évolue à l'ancienneté, telle qu elle peut être appréciée à une date donnée sur la base d'anticipations statiques, pour estimer la valeur d'une carrière. Les calculs de valeur des carrières montrent que si ces dernières ne se sont pas dévalorisées fortement en termes bruts sur la période étudiée, elles ont cependant subi, en termes nets, une succession de hausses et de baisses sans aucune rationalité rente. Une analyse économétrique élémentaire suggère que les journées de grève sont « cause » des augmentations de valeur et qu elles sont elles-mêmes « causées » par les baisses de valeur et les hausses d'effectifs.
Une analyse de la dimension réseau des fragilités bancaires et financières

Published: May 2011

A Network Analysis of Banking and Financial Fragilities

This literature overview on banking fragilities highlights the fact that including a network perspective is a way to better understand the nature of banking risks. Banks embed in networks of interbank relations, but the part played by these networks in issues such as liquidity distribution, or bankruptcy contagion is largely undervalued. It seems however network architecture is a key variable to measure both liquidity and insolvency risks. The analysis of the network topology is thus to be taken into account in financial policies tackling banking crisis.
Quels instruments pour une politique environnementale ?
Authors: Saint-Paul Gilles
Published: May 2011

Dans cet article, on utilise un modèle simple pour étudier le rôle respectif de la taxation et de la subvention à la recherche-développement « verte » pour réduire la pollution. On montre qu'il est optimal d'utiliser ces deux instruments simultanément. La taxation pigovienne sur les émissions ne suffit pas en dépit de ses effets induits sur l'innovation verte. Une subvention à l'innovation verte en plus des subventions usuelles à la recherche-développement permet de jouer sur la marge extensive d'émissions de polluants ainsi que de corriger la sous-évaluation par les agents privés de la différence de surplus social entre innovation verte et innovation polluante.

L'objectif de cet article est de comprendre comment les interactions sociales concourent à l'économie d'Internet et en particulier à la dynamique de diffusion des usages en ligne. L'étude des comportements d'adoption permet aussi de mieux appréhender les modèles d'affaires des entreprises présentes sur Internet. Là encore, les interactions sociales, sous la forme d'exter- nalités de réseau, de bouche-à-oreille et d'évaluation jouent un rôle central, en créant la confiance nécessaire aux échanges et en stimulant la demande s'adressant aux entreprises.
Incitations et licenciement individuel
Authors: Gabuthy Yannick , Lambert Eve-Angéline
Published: May 2011

Cet article présente une revue de la littérature consacrée à l'étude des effets de la protection de l'emploi, relative notamment au licenciement individuel, sur le comportement des agents économiques impliqués dans la relation de travail. Ces analyses montrent que les règles juridiques encadrant la rupture de cette relation ne sont pas neutres. En effet, elles influencent non seulement le comportement des protagonistes lors de cette éventuelle rupture (que ce soit dans le choix du mode de séparation ou dans la négociation des indemnités de licenciement qui en découle) mais également la relation de travail (notamment en termes d'incitations à l'investissement spécifique). A cet égard, toute politique législative devrait tenir compte de cette capacité réactive des agents économiques afin de structurer efficacement les règles juridiques relatives au licenciement individuel.
Contractualiser l'ouverture des forêts privées au public ?
Authors: Rambonilaza Mbolatiana , Gadaud Juliette , Point Patrick
Published: May 2011

La forêt reste la destination de loisirs privilégiée des Français. Face à la croissance de la demande, la loi d'orientation sur la forêt de 200 1 se tourne vers les forêts privées. Pour assurer la compatibilité de l'ouverture récréative avec les autres fonctions de la forêt, elle prévoit le versement aux forestiers d'une compensation pour services rendus. Après six ans d'existence de la loi, peu de conventions ont vu le jour car collectivités publiques et représentants des propriétaires disposent de peu d'éléments de référence pour définir les termes des conventions. Après avoir exposé le concept de consentement à recevoir comme fondement de la compensation dans le cadre des services récréatifs non marchands, cet article livre quelques indications sur les actions et les montants des contreparties financières à verser aux propriétaires. Il relève la disparité des attentes individuelles et l'ampleur relative du coût financier de l'application de la loi comparé au bénéfice non marchand de cette fonction sociale, estimé à 2 milliards d'euros par an.
L'immigration a-t-elle un effet sur les finances publiques ?
Authors: Monso Olivier
Published: May 2011

Does Immigration have an Effect on Public Finance ?

This paper tries to assess the impact on public finance of an immigrant coming to France. It enlightens the advantages of a dynamic approach, in which all taxes and social protection benefits are taken into account along the life cycle and illustrates in particular the potential contribution for public finance from young, qualified immigrant workers. The impact of immigration on public finance is difficult to determine, but whether positive or negative, its magnitude seems to be small. In the long run, the advantage coming from the fact that ages where people are on the labour force are strongly represented among new migrants is offset by the fact that they are less educated than young natives and form larger families, and principally because they have weaker employment rates and wages, controlling for education. Provided the methodological difficulties this method faces, it seems difficult to use it to inspire the migration policy.
Réforme du droit social et efficacité économique
Authors: Barthélémy Jacques , Cette Gilbert
Published: May 2011

Les principaux objectifs d'une réforme du droit social sont d'encourager la négociation collective, de réduire la complexité du droit du travail, de ne pas affaiblir sa fonction protectrice, de maintenir les hétérogénéités quand elles répondent à des besoins et des attentes, de réduire les sources d'inégalités que le droit social peut créer et de limiter les nombreux effets de seuils. Les principaux écueils à éviter sont ceux du développement d'un arsenal dirigiste, d'une confiance exagérée dans le contrat et d'une non prise en compte des attentes des personnes concernées mais aussi des contraintes juridiques incontournables, tant nationales qu'internationales. L'orientation essentielle d'une réforme ambitieuse du droit social respectant ces objectifs et évitant ces écueils passe par un développement du droit dérogatoire. Ce développement permettrait la contraction du droit réglementaire et, simultanément, le développement du droit conventionnel, pour aboutir à une flexibilité négociée, gérée par les partenaires sociaux eux-mêmes. Pour que cette promotion du droit conventionnel soit effective, il faut accorder aux partenaires sociaux des rentes associées à la négociation : flexibilités juridiques, financières... les incitant à construire du droit contractuel. Des illustrations concrètes d'une telle réforme sont fournies dans cinq domaines : la durée du travail, le salaire minimum, les garanties sociales face aux précarités, l'emploi précaire et les coûts et incertitudes de la judiciarisation des licenciements.
Rémunération et sélection de la main-d'œuvre
Authors: Teyssier Sabrina
Published: May 2011

Comme Saint-Paul [2001] montre que des travailleurs avec des niveaux de productivité proches ont tendance à se retrouver dans les mêmes firmes, on peut s'interroger sur le pouvoir sélectif des mécanismes de rémunération. Le modèle théorique de Lazear [2000] met en avant l'existence à la fois des effets d'incitation et de sélection d'un mode de rémunération indexé sur la performance des employés. Ce modèle a été testé à l'aide de différentes méthodes d'estimation et la majorité d'entre elles supportent les prédictions théoriques. Ce modèle a été étendu à des travaux théoriques et empiriques supportant l'hypothèse d'auto-sélection des travailleurs en fonction de leurs caractéristiques intrinsèques telles que l'aversion au risque, la motivation intrinsèque ou encore les préférences sociales. Enfin, il est montré que l'hétérogénéité de la main-d'œuvre contribue à l'efficience du marché si les travailleurs s'auto-sélectionnent dans différentes organisations.

Disaster Preparedness for Nurses: A Teaching Guide
Authors: Tillman Paula
Published: May 2011

As one of the largest groups of health care providers in the United States, nurses are trained to attend to the physical, psychological, and spiritual needs of their patients, making them highly qualified to influence the outcomes of victims of an emergency situation. Unfortunately, nursing programs offer limited content on delivering care under extreme conditions, and few continuing education programs are available to practicing nurses. This article provides a brief educational presentation that can be used without an extensive time commitment or in-depth instructor knowledge of the subject. The course content has been presented to nurses at the American Red Cross, at local chapter meetings of professional nursing organizations, and to both graduate and undergraduate nursing students. This presentation is not designed to be a comprehensive study of disaster nursing, but serves as a starting point that might lead to further study and encourage active participation in preparedness education and planning.

Published: May 2011

Many schools of nursing have implemented standardized testing using platforms such as those developed by Assessment Technologies Institute (ATI) to better prepare students for success on the National Council Licensure Examination for Registered Nurses® (NCLEX-RN). This study extends and replicates the research on standardized testing to predict first-time pass success in a diverse student population and across two prelicensure program types. The final sample consisted of 589 students who graduated between 2003 and 2009. Demographic data, as well as academic performance and scores on the ATI RN Comprehensive Predictor, were analyzed. The findings in this study indicate that scores on the ATI RN Comprehensive Predictor were positively, significantly associated with first-time pass success. Students in jeopardy of failing the NCLEX-RN on their first attempt can be identified prior to graduation and remediation efforts can be strengthened to improve their success.
Success in Nursing School: Black Nursing Students’ Perception of Peers, Family, and Faculty
Authors: Dapremont Jill A.
Published: May 2011

Blacks comprise 12.3% of the U.S. population and only 4.6% of registered nurses nationally. Moreover, Blacks have the highest percentage of nongraduates among nursing students compared with other U.S. racial/ethnic groups. This descriptive qualitative study examined the perceptions and experiences that contributed to success for Black graduates, ages 18 to 50, who attended nursing degree programs with predominantly White students and identified the experiences students credited for their success. Data were collected using semi-structured in-depth interviews with 18 participants. Categories and patterns were established using content analysis. Findings suggest that the Black students valued peer support, interactions with White students’ study groups, family support, and faculty encouragement and support as factors that enhanced success. This article focuses on those supports students identified as essential to graduation. The findings of this study demonstrate that it takes a community to create a nurse. Specific implications for student retention are discussed.

In karst area, geology condition is complex, karst phenomena develop, underground water is prolific, even underground river and channel exist, rock surface fluctuates up and down in a large level, which will seriously influence type of pile foundation, construction quality as well as pile foundation safety. Pile foundation construction is considerably difficult and severe hidden quality fault may occur. If rock-embedded end-bearing pile on hard rock or limestone can satisfy design requirement depends mainly on integrity of bedrock beneath pile end, pile body concrete quality and settled material beneath pile end, which are the key items for rock-embedded pile test. Using acoustic wave transmission method and core sample method, integrity of bedrock beneath pile end, pile body concrete quality and settled material beneath pile end can be tested, which can not only reflect quality and bearing capacity of single pile, but also assess bearing capacity of all foundation piles in the whole ground.

Authors: Zhang Ning , Ning Xu Nan , Zhou Jian Bo , Wei Pei Tao , Luo Hai Jian
Published: May 2011

The combustion characteristics of the mixtures, which are made from different proportions of paper mill sludge and coal, were studied by the thermogravimetric analysis (TG-DTG) at different heating rates. The results showed that there were obviously three temperature zones in the paper mill sludge combustion curves, which is respectively corresponding to two devolatilization stages and a fixed carbon combustion stage. In these stages, the weight of sludge was lost promptly. When the proportions of sludge – coal blends were rather different, ignition point obviously shifted to the larger proportions, and DTG curve was more closed to the larger proportions. During the combustion process of the mixture, the paper mill sludge and the coal had basically maintained their own devolatilisation characteristics. And the comprehensive combustion characteristic index S of sludge-coal blend declined, demonstrating that higher volatility had better combustion characteristics. As the heating rate and the proportions of coal increasing, total weight loss rate increased, while burnout index Cb raised.

Vehicle suspension system with hysteretic nonlinearity has obvious nonlinear characteristics, which directly cause the system to the possibility of existence of bifurcation and chaos. Two degrees of freedom for the 1/4 body suspension model is established and the behavior of the system under road multi-frequency excitations is analyzed. In the paper, it reveals the existence of chaos in the system with the Poincaré map, phase diagram, time history graph, and its chaotic behavior is controlled by nonlinear feedback. Numerical simulation shows the effectiveness and feasibility of the control method with improved ride comfort. The results may supply theoretical bases for the analysis and optimal design of the vehicle suspension system.
Effect of La2O3 and CeO2 on Morphology of Graphite in Cast Iron
Authors: Zhang Suo Mei , Wang Zi Dong
Published: May 2011

Pure carbon, pure iron and single crystall silicon were firstly loaded into a pure graphite crucible to obtain a hypereutectic Fe-C melt by carburizing at high temperatures in this paper. The powder of oxide La2O3 and CeO2 were added respectively to the melt under the same process conditions and cast iron samples were obtained. The graphite morphology of the samples was observed under optical microscope and SEM. Matrix of the samples were etched by electrolysis way. At last non-ferrous residue on the surface of cast iron samples was gathered, calcined,observed under SEI and BEI and analysed with EDS to find the trace of oxide La2O3 or CeO2. The results showed that oxide La2O3 or CeO2 was really added into the melt but the morphology of graphite did not change. The only effect of the oxides was making the amount of graphiteto increase slightly. All the results of this paper indicat that the oxide La2O3 or CeO2 is possibly the base for graphite flake to precipitate but is not a sufficient condition for graphite to nodularize.
