Employer occupation of regulatory space of the Employee Information and Consultation (I&C) Directive in liberal market economies

This article shows how both employers and the state have influenced macro-level processes and structures concerning the content and transposition of the European Union (EU) Employee Information and Consultation (I&C) Directive. It argues that the processes of regulation occupied by employers reinforce a voluntarism which marginalizes rather than shares decision-making power with workers. The contribution advances the conceptual lens of ‘regulatory space’ by building on Lukes’ multiple faces of power to better understand how employment regulation is determined across transnational, national and enterprise levels. The research proposes an integrated analytical framework on which ‘occupancy’ of regulatory space can be evaluated in comparative national contexts.

K&C局部损伤混凝土材料模型在精细有限元模拟中的应用

This paper presents a study on concrete fracture and the associated mesh sensitivity using the finite element (FE) method with a local concrete model in both tension (Mode I) and compression.To enable the incorporation of dynamic loading, the FE model is developed using a transient dynamic analysis code LS-DYNA Explicit.A series of investigations have been conducted on typical fracture scenarios to evaluate the model performances and calibration of relevant parameters.The K&C damage model was adopted because it is a comprehensive local concrete model which allows the user to change the crack band width, fracture energy and rate dependency of the material.Compressive localisation modelling in numerical modelling is also discussed in detail in relation to localisation.An impact test specimen is modelled.

Estudo sobre a ocorrência de enterobactérias produtoras de ESBL isoladas de pacientes internados em unidades de pós-operatório de cirurgia cardíaca de um hospital da rede pública do Rio de Janeiro

As infecções associadas aos cuidados de saúde constituem um problema grave nas unidades hospitalares bem como nos serviços de atendimento extra-hospitalares. Diferentemente de outros países, no Brasil, existe uma incidência alta dessas infecções causadas por microorganismos Gram-negativos produtores de β-lactamase de espectroestendido (ESBL). Estas enzimas hidrolisam compostos β-lactâmicos e são consideradas mundialmente como de importância clínica, pois a localização de seus genes emelementos móveis facilitam a transmissão cruzada. Este estudo foi realizado com amostras bacterianas isoladas de material clínico e de fezes de pacientes internados em um hospital da rede pública no Rio de Janeiro, Brasil. Estes pacientes estavam internados em duas unidades de terapia intensiva cardiológica, no período de janeiro a dezembro de 2007. O estudo teve por objetivo realizar a caracterização fenotípica e genotípica desses isolados associados à colonização ou infecção dos pacientes. Os testes fenotípicos e genotípicos foram realizados na Universidade do Estado do Rio de Janeiro e incluíram provas bioquímicas, teste de susceptibilidade, teste confirmatório para a expressão da produção da enzima ESBL e Reação de Polimerase em Cadeia (PCR) com iniciadores específicos para cinco genes: blaTEM, blaSHV, CTX-M1, Toho1 e AmpC. As espécies bactérianas mais frequentemente isoladas foram Escherichia coli (25%) e Klebsiella pneumoniae (30,56%), e os genes mais prevalentes foram blaTEM (41,6%), AMPC (41,6%) blaSHV (33,3%), CTX-M1 (25%), e Toho1 (19,44%). Identificamos em 25% das amostras enterobactérias que não eram E. coli, K. pneumoniae ou Proteus sp, com fenótipo para ESBL e a expressão dos mesmos genes, confirmando a necessidade de investigação nestes grupos microbianos. O substrato mais sensível para a expressão da área de sinergismo no Teste de Aproximação foi o ceftriaxone (80%). Identificamos também que 17% das amostras positivas para ESBL apresentaram co-produção para AmpC e 50% apresentaram mais de um gene para os iniciadores testados. A presença da carbapenemase foi avaliada em amostras bacterianas com susceptibilidade intermediária para ertapenem, através do Teste de Hodge modificado. Os achados do presente estudo caracterizaram a co-produção de AmpC e ESBL, bem como sugerem a necessidade da revisão e a ampliação dos métodos para a detecção de outros padrões de resistência na nossa Instituição.

Regulating for mutual gains? Non-union employee representation and the Information and Consultation Directive

Interest in ‘mutual gains’ has principally been confined to studies of the unionised sector. Yet there is no reason why this conceptual dynamic cannot be extended to the non-unionised realm, specifically in relation to non-union employee representation (NER). Although extant research views NER as unfertile terrain for mutual gains, the paper examines whether NER developed in response to the European Directive on Information and Consultation (I&C) of Employees may offer a potentially more fruitful route. The paper examines this possibility by considering three cases of NER established under the I&C Directive in Ireland, assessing the extent to which mutual gains were achieved.

Assessing the needs of informal caregivers to cancer survivors: a review of the instruments

Objective: Cancer may impact negatively on an informal caregiver's health long after treatment has ended. This review identifies the self-report measures currently in use to measure caregivers need for support and determines their scientific soundness and clinical utility.

Method: A systematic electronic database search of Medline, CINAHL, PsychINFO, BNI ProQuest was conducted. The psychometric properties and clinical utility of needs assessment tools for caregivers of cancer survivors (excluding advanced disease) were extracted and summarised.

Results: Seven cancer survivor caregiver needs assessment tools were identified. Data on instrument development was well reported, although variability was noted in their structure and content. The majority demonstrated some degree of reliability and validity; only two were evaluated for test–retest reliability (CaSPUN and SPUNS) with only the SPUNS showing a high degree of reliability over time. The Health Care Needs Survey (HCNS), Needs Assessment of Family Caregivers-Cancer (NAFC-C) and Cancer Caregiving Tasks Consequences and Needs Questionnaire (CaTCoN) have been validated at various stages of the cancer continuum. Minimal data was available on responsiveness.

Conclusion: All assessment tools identified require further psychometric analysis. For research purposes, the use of the SPUNS (with its acceptable test–retest reliability) appears most appropriate; although its length may be of concern for clinical use; therefore, the shorter SCNS-P&C is likely to be more suitable for use clinically. At present, the NAFC-C demonstrates a great potential in both the research and clinical environments; however, it requires further psychometric testing before it can be fully recommended. Further analysis is necessary on ideal response formats and the meaning of a total needs score.

Modelling Static and Dynamic FRP-Concrete Bond Behaviour Using a Local Concrete Damage Model

This paper presents a study on the bond behaviour of FRP-concrete bonded joints under static and dynamic loadings, by developing a meso-scale finite element model using the K&C concrete damage model in LS-DYNA. A significant number of single shear experiments under static pull-off loading were modelled with an extensive parametric study covering key factors in the K&C model, including the crack band width, the compressive fracture energy and the shear dilatation factor. It is demonstrated that the developed model can satisfactorily simulate the static debonding behaviour, in terms of mesh objectivity, the load-carrying capacity and the local bond-slip behaviour, provided that proper consideration is given to the selection of crack band width and shear dilatation factor. A preliminary study of the effect of the dynamic loading rate on the debonding behaviour was also conducted by considering a dynamic increase factor (DIF) for the concrete strength as a function of strain rate. It is shown that a higher loading rate leads to a higher load-carrying capacity, a longer effective bond length, and a larger damaged area of concrete in the single shear loading scenario.

Triggering employee voice under the European Information and Consultation Directive: A non-union case study

The transposition of the 2002/14/EC Directive, establishing a general framework for information and consultation (I&C), has proven contentious in largely voluntarist systems of employment regulation. Receiving particular criticism is the employee ‘opt-in’ mechanism as a means to access I&C rights. For non-union employees in particular, the ability and potential to negotiate rights for I&C is widely seen to be problematic. This article uniquely examines the opt-in mechanism in the context of non-unionism, considering how non-union employers respond to non-union employees invoking their legislative rights to I&C. Drawing upon a case study conducted over four years in a large non-union multinational, the evidence shows how the opt-in and negotiation process function to the advantage of the employer rather than the intended regulatory impact to advance employee rights

Species concepts in Cercospora: spotting the weeds among the roses

The genus Cercospora contains numerous important plant pathogenic fungi from a diverse range of hosts. Most species of Cercospora are known only from their morphological characters in vivo. Although the genus contains more than 5 000 names, very few cultures and associated DNA sequence data are available. In this study, 360 Cercospora isolates, obtained from 161 host species, 49 host families and 39 countries, were used to compile a molecular phylogeny. Partial sequences were derived from the internal transcribed spacer regions and intervening 5.8S nrRNA, actin, calmodulin, histone H3 and translation elongation factor 1-alpha genes. The resulting phylogenetic clades were evaluated for application of existing species names and five novel species are introduced. Eleven species are epi-, lecto- or neotypified in this study. Although existing species names were available for several clades, it was not always possible to apply North American or European names to African or Asian strains and vice versa. Some species were found to be limited to a specific host genus, whereas others were isolated from a wide host range. No single locus was found to be the ideal DNA barcode gene for the genus, and species identification needs to be based on a combination of gene loci and morphological characters. Additional primers were developed to supplement those previously published for amplification of the loci used in this study. TAXONOMIC NOVELTIES: New species - Cercospora coniogrammes Crous & R.G. Shivas, Cercospora delaireae C. Nakash., Crous, U. Braun & H.D. Shin, Cercospora euphorbiae-sieboldianae C. Nakash., Crous, U. Braun & H.D. Shin, Cercospora pileicola C. Nakash., Crous, U.

Relationship between race and clinical characteristics, extent of disease, and response to chemotherapy in patients with low-risk gestational trophoblastic neoplasia

Objective. To evaluate the potential effects of race on clinical characteristics, extent of disease, and response to chemotherapy in women with postmolar low-risk gestational trophoblastic neoplasia (GTN).Methods. This non-concurrent cohort study was undertaken including patients with FIGO-defined postmolar low-risk GTN treated with comparable doses and schedules of chemotherapy at the New England Trophoblastic Disease Center (NETDC) between 1973 and 2012. Racial groups investigated included whites, African American and Asians. Information on patient characteristics and response to chemotherapy (need for second line chemotherapy, reason for changing to an alternative chemotherapy, number of cycles/regimens, need for combination chemotherapy, and time to hCG remission) was obtained.Results. Of 316 women, 274 (86.7%) were white, 19 (6%) African American, and 23 (7.3%) Asian. African Americans were significantly younger than white and Asian women (p = 0.008). Disease presentation, and extent of disease, including antecedent molar histology, median time to persistence, median hCG level at persistence, rate of D&C at persistence, presence of metastatic disease, and FIGO stage and risk score were similar among races. Need for second line chemotherapy (p = 0.023), and median number of regimens (p = 0.035) were greater in Asian women than in other races.Conclusions. Low-risk GTN was more aggressive in Asian women, who were significantly more likely to need second line chemotherapy and a higher number of chemotherapy regimens to achieve complete remission than women of African American and Asian descent. Further studies involving racial differences related to clinical, biological and environmental characteristics are needed. (C) 2015 Published by Elsevier Inc.

Soft [beta]-adrenoceptor agonists for topical use in psoriasis

Psoriasis is characterised by epidermal proliferation and inflammation resulting in the appearance of elevated erythematous plaques. The ratio of c~AMP/c~GMP is decreased in psoriatic skin and when the epidermal cell surface receptors are stimulated by β-adrenergic agonists, intracellular ATP is transformed into c-AMP, thus restoring the c~AMP/c~GMP levels. This thesis describes a series of β-adrenoceptor agonists for topical delivery based upon the soft-drug approach. Soft drugs are defined as biologically active, therapeutically useful chemical compounds (drugs) characterised by a predictable and controllable In vivo destruction (metabolism) to non-toxic moieties. after they achieve their therapeutic role, The N-substituent can accommodate a broad range of structures and here the alkoxycarbonylethyl group has been used to provide metabolic susceptability. The increased polarity of the dihydroxy acid, expected after metabolic conversion of the soft~drug, ethyl N-[2'-(3',4'-dihydroxyphenyl)-2'-hydroxyethyl]-3- aminopropionate, should eliminate agonist activity. Further. to prevent oxidation and enhance topical delivery, the catechol hydroxyl groups have been esterified to produce a pro-soft-drug which generates the soft-drug in enzymic systems. The chemical hydrolysis of the pro-soft-drug proceeded via the formation of the dlpivaloyloxy acid and it failed to generate the active dihydroxy ester soft-drug. In contrast, in the presence of porcine liver carboxyesterase, the hydrolysis of the pro-soft drug proceeded via the formation of the required active soft-drug. This compound, thus, has the appropnate kinetic features to enable it to be evaluated further as a drug for the treatment of psoriasis. The pH rate-profile for the hydrolysis of soft-drug indicated a maximum stability at pH ∼ 4.0. The individual rate constants for the degradation and the pKa were analysed by nonlinear regression. The pKa of 7.40 is in excellent agreement with that determined by direct titration (7.43) and indicates that satisfactory convergence was achieved. The soft-drug was poorly transported across a silicone membrane; it was also air-sensitive due to oxidation of the catechol group. The transport of the pro-soft-drug was more efficient and, over the donor pH range 3-8, increased with pH. At lower values, the largely protonated species was not transported. However, above pH 7. chemical degradation was rapid so that a donor pH of 5-6 was optimum. The β-adrenergic agonist activity of these compounds was tested in vitro by measuring chronotropic and inotropic responses in the guinea pig atria and relaxation of guinea pig trachea precontracted with acetylcholine (10-3 M). The soft~drug was a full agonist on the tracheal preparation but was less potent than isoprenaline. Responses of the soft~drug were competitively antagonised by propranolol (10-6 M). The soft~drug produced an increase in force and rate of the isolated atrial preparatIon. The propyl analogue was equally potent with ED50 of 6.52 x 10-7 M. In contrast, at equivalent doses, the dihydroxy acid showed no activity; only a marginal effect was observed on the tracheal preparation. For the pro~soft-drug, responses were of slow onset, in both preparations, with a slowly developing relaxatlon of the tracheal preparatlon at high concentrations (10-5 M). This is consistent with in vitro results where the dipivaloyl groups are hydrolysed more readily than the ethyl ester to gIve the active soft-drug. These results confirm the validity tif the pro-soft-drug approach to the deUvery of β-adrenoceptor agonists.

Intercepting Cyclic Dinucleotide Signaling with Small Molecules

Bacterial infections, especially the ones that are caused by multidrug-resistant strains, are becoming increasingly difficult to treat and put enormous stress on healthcare systems. Recently President Obama announced a new initiative to combat the growing problem of antibiotic resistance. New types of antibiotic drugs are always in need to catch up with the rapid speed of bacterial drug-resistance acquisition. Bacterial second messengers, cyclic dinucleotides, play important roles in signal transduction and therefore are currently generating great buzz in the microbiology community because it is believed that small molecules that inhibit cyclic dinucleotide signaling could become next-generation antibacterial agents. The first identified cyclic dinucleotide, c-di-GMP, has now been shown to regulate a large number of processes, such as virulence, biofilm formation, cell cycle, quorum sensing, etc. Recently, another cyclic dinucleotide, c-di-AMP, has emerged as a regulator of key processes in Gram-positive and mycobacteria. C-di-AMP is now known to regulate DNA damage sensing, fatty acid synthesis, potassium ion transport, cell wall homeostasis and host type I interferon response induction. Due to the central roles that cyclic dinucleotides play in bacteria, we are interested in small molecules that intercept cyclic dinucleotide signaling with the hope that these molecules would help us learn more details about cyclic dinucleotide signaling or could be used to inhibit bacterial viability or virulence. This dissertation documents the development of several small molecule inhibitors of a cyclic dinucleotide synthase (DisA from B. subtilis) and phosphodiesterases (RocR from P. aeruginosa and CdnP from M. tuberculosis). We also demonstrate that an inhibitor of RocR PDE can inhibit bacterial swarming motility, which is a virulence factor.

Perfil epidemiológico y análisis de la formulación antibiótica en pacientes con infección urinaria nosocomial en la Fundación Cardioinfantil en el año 2014

Introducción: La IVU es muy frecuenten en la (FCI - IC), Alrededor el 60% de los pacientes con diagnóstico de IVU nosocomial corresponden a gérmenes resistente, Desde el año 2010 el CLSI disminuyó los puntos de corte de sensibilidad en las enterobacteriaceae y removió la necesidad de tamizaje y confirmación de (BLEE), en el presente trabajo se pretende determinar el perfil epidemiológico de la formulación antibiótica en pacientes con IVU nosocomial. Diseño: Se realizó un estudio observacional analítico de corte transversal. Métodos: Se realizó un análisis univariado, bivariado y multivariado. El análisis bivariado y multivariado se realizó para determinar la medida de asociación teniendo en cuenta la formulación de Carbapenemico la variable dependiente, evaluándose mediante chi cuadrado. Resultados: Se revisaron 131 urocultivos, se incluyeron 116. Los aislamientos microbiológicos más frecuentemente encontrados fueron E. Coli y K. Pneumoniae, el 43.4% de los aislamientos, presentaron expresión de BLEE, 90% de los aislamientos fueron sensibles a Cefepime. La mayoría de los modelos obtenidos mostraron una fuerte asociación entre el reporte de BLEE en antibiograma con la formulación de carbapenémicos como terapia final OR 33,12 IC 95% (2,90 – 337,4). Conclusión: La epidemiologia de la IVU nosocomial en la FCI-IC no difiere de las referencias internacionales, no hay adherencia a las guías de manejo intrahospitalario y el reporte de la palabra BLEE en el antibiograma predice la formulación de antibiótico carbapenémico por el médico que lee el urocultivo
