What Kind of Justice Today ? Expectations Of 'Good Justice', Convergences And Divergences Between Managerial And Judicial Actors And How They Fit Within Management-Oriented Values

This research aims toward a better understanding of the organizational culture(s) of the judiciary in Switzerland by analysing what 'good justice' means nowadays in this country. It seeks to clarify whether, and to what extent, expectations of 'good justice' of judicial actors (judges without managerial experience) and of managerial actors (court managers) are similar and to describe possible managerial implications that may result from this. As judges are at the heart of the judicial organization and exert a strong influence on other groups of actors (Sullivan, Warren et al. 1994), the congruence of their expectations with those of court managers will be at the centre of the analysis. Additionally, referring to the conceptual worlds of Boltanski and Thévenaut (1991), we analyze how closely these expectations are to management-oriented values. We found that almost half of expectations are common to the two groups examined and the main quoted ones are compatible to new public management (NPM) concepts. On the other hand, those expectations shared exclusively by judges relate to the human side of justice, whereas those specific to court managers focus on the way justice functions.

Mycobacterium avium restriction fragment lenght polymorphism-IS IS1245 and the simple double repetitive element polymerase chain reaction typing method to screen genetic diversity in Brazilian strains

Simple double repetitive element polymerase chain reaction (MaDRE-PCR) and Pvu II-IS1245 restriction fragment length polymorphism (RFLP) typing methods were used to type 41 Mycobacterium avium isolates obtained from 14 Aids inpatients and 10 environment and animals specimens identified among 53 mycobacteria isolated from 237 food, chicken, and pig. All environmental and animals strains showed orphan patterns by both methods. By MaDRE-PCR four patients, with multiple isolates, showed different patterns, suggesting polyclonal infection that was confirmed by RFLP in two of them. This first evaluation of MaDRE-PCR on Brazilian M. avium strains demonstrated that the method seems to be useful as simple and less expensive typing method for screening genetic diversity in M. avium strains on selected epidemiological studies, although with limitation on analysis identical patterns except for one band.

Evaluation of MRSA-Screen, a simple anti-PBP 2a slide latex agglutination kit, for rapid detection of methicillin resistance in Staphylococcus aureus.

The MRSA-Screen test (Denka Seiken Co., Ltd., Tokyo, Japan), consisting of a slide latex agglutination kit that detects PBP 2a with a monoclonal antibody, was blindly compared to the oxacillin disk diffusion test, the oxacillin-salt agar screen, and PCR of the mecA gene for the detection of methicillin resistance in Staphylococcus aureus. A total of 120 methicillin-susceptible S. aureus (MSSA) and 80 methicillin-resistant S. aureus (MRSA) isolates, defined by the absence or presence of the mecA gene, respectively, were tested. The MRSA-Screen test, the oxacillin disk diffusion test, and the oxacillin-salt agar screening test showed sensitivities of 100, 61.3, and 82.5% and specificities of 99.2, 96.7, and 98.3%, respectively. We conclude that the MRSA-Screen is a very accurate, reliable, and fast test (15 min) for differentiation of MRSA from MSSA colonies on agar plates.

Using the costs of drug therapy to screen patients for a community pharmacy-based medication review program

Objectives: To measure the positive predictive value (PPV) of the cost of drug therapy (threshold = 2000 Swiss francs [CHF], US$1440, <euro>1360) as a screening criterion for identifying patients who may benefit from medication review (MR). To describe identified drug-related problems (DRPs) and expense problems (EPs), and to estimate potential savings if all recommendations were accepted. Setting Five voluntary Swiss community pharmacies. Methods: Of 12,680 patients, 592 (4.7%) had drug therapy costs exceeding 2000 CHF over a six-month period from July 1 to December 31, 2002. This threshold limit was set to identify high-risk patients for DRPs and EPs. Three pharmacists consecutively conducted a medication review based on the pharmaceutical charts of 125 sampled patients who met the inclusion criterion. Main outcome measure: The PPV of a threshold of 2000 CHF for identifying patients who might benefit from a MR: true positives were patients with at least one DRP, while false positives were patients with no DRP. Results: The selection based on this criterion had a PPV of 86% for detecting patients with at least one DRP and 95% if EPs were also considered. There was a mean of 2.64 (SD = 2.20) DRPs per patient and a mean of 2.14 (SD = 1.39) EPs per patient. Of these patients, 90% were over 65 years old or were treated with at least five chronic medications, two common criteria for identifying patients at risk of DRPs. The main types of DRPs were drug-drug interactions, compliance problems and duplicate drugs. Mean daily drug cost per patient was CHF 14.87 (US$10.70, <euro>10.10). A potential savings of CHF 1.67 (US$1.20, <euro>1.14) per day (11%) was estimated if all recommendations to solve DRPs and EPs suggested herein were implemented. Conclusion: Further studies should investigate whether the potential benefit of medication reviews in preventing DRPs and containing costs in this patient group can be confirmed in a real practice environment.

Tri-sector partnerships in social entrepreneurship: discourse and practice of the actors from the circles of action and reflection

This article discusses the construction of tri-sector partnerships in three projects conducted in Brazil in different fields of intervention of public policy (access to water, basic education and performance of boards of rights of children and adolescents). Collaborative articulations involving the players from three sectors (the State, civil society and the market) are practices that are little studied in the Brazilian and even in the international context, as tri-sector partnerships are rare, despite the proliferation of lines of discourse in support of alliances between governments and civil society or between companies and NGOs in the management of public policy. As a research strategy, this study resorted to cooperative inquiry, a method that involves breaking down the boundaries between the subjects and the objects of the analysis. Besides working toward a better understanding of the challenges of building tri-sector partnerships in the Brazilian context, the article also tries to show the relevance to public policy studies of investigative methods based on the subjects studied, as a means of developing an understanding of the practices, lines of discourse and dilemmas linked to social action in social programs.

From print to screen: changes and challenges facing the Brazilian publishing industry

The publishing industry is at a turning point. Facing the first major disruptive innovation in five centuries, its long-established structure and business model are at stake. Building on literature based on the pitfalls for incumbents, we interviewed key executives from the major publishers in Brazil to understand their perspective. We find that not only are they facing those pitfalls, but we also propose a new one, The Industry View Trap, concerning challenges created by convergence, the difficulty to deal with changes in the ecosystem and the fact that the very definition of the industry you're part of might have changed.

Use of non-invasive ambulatory blood pressure monitoring to screen for high-risk hypertensive patients.

Blood pressures measured casually by a doctor often differ considerably from those recorded during everyday activities away from the medical environment. In the present study, we compared office and ambulatory recorded pressures in 475 consecutive untreated patients diagnosed hypertensive by physicians. Blood pressure monitored non-invasively during the day was, on average 15/7 mmHg lower than the corresponding office pressures. The difference between office and ambulatory recorded pressure tended to be greatest in those patients with the highest office blood pressure levels, although the relationship between the two types of measurement was too weak (r = 0.50 and 0.38 for systolic and diastolic pressure, respectively) to have any predictive value in the individual patient. Office blood pressures were at least 10 mmHg higher than ambulatory pressures in 62% of patients for systolic and 42% for diastolic pressure. Blood pressure levels recorded during ambulatory monitoring were higher than in the doctor's office for 18% of patients for systolic and 22% for diastolic pressure. Among patients with systolic pressures of between 161 and 180 mmHg or diastolic pressures between 96 and 105 mmHg when facing a doctor, 27 and 37% respectively, showed markedly lower systolic (less than 140 mmHg) or diastolic (less than 90 mmHg) ambulatory recorded pressures. These data therefore indicate that ambulatory blood pressure monitoring may help to identify those truly hypertensive patients who are most likely to benefit from antihypertensive therapy.

Identification, using a siRNA screen approach, and molecular characterization of a new Fas pathway modulator: STK11/

Abstract : Apoptosis is an evolutionarily conserved cellular suicide mechanism that can be triggered by activation of various pathways, such as the Fas-Pathway. Upon stimulation by its specific ligand (FasL), present at the surface of Cytotoxic Τ lymphocytes, the death receptor Fas initiates a signaling cascade culminating in the activation of cellular caspases, leading thus to cell death of the target cell (e.g. transformed cell). Dysregulation of apoptosis in general, and of Fas pathway in particular, was shown to contribute to pathogenesis of cancers and many human diseases. Even though, during the last decades the molecular mechanisms of apoptosis have been widely studied, it is important to better understand the mechanisms leading to apoptosis, to improve our understanding of pathological processes, and generate more subtle apoptosis-modulating therapies to fight cancer and other diseases. In order to identify new components of the Fas signaling pathway, a screen based on the mechanism of RNA interference was undertaken. After a first and a second manual whole-kinome screen, we identified several strong positive hits that showed a protection against Fas ligand-induced apoptosis with distinct siRNAs, notably STK11, an interesting tumor suppressor mutated in several sporadic and inherited cancers. The STK11 functional characterization reveals that this kinase represents an apically acting general pro-apoptotic modulator of the extrinsic pathway (FasL, TRAIL, TNF-induced apoptosis), but not of the intrinsic apoptotic pathway. The STK11 action on the Fas pathway was shown to be dependent on its kinase activity, but independent of AMPK, a well-characterized STK11 downstream substrate. Furthermore, STK11 was shown to interact with caspase-8, a major mediator of the extrinsic pathway, and modulate its activity through an unclear mechanism that may involve an STK11-dependant caspase-8 phosphorylation. This modification may allow a proper caspase-8 polyubiquitination and activation in p62 sequestosmes aggregates, but may also increase the activation of caspase-8 at the DISC level. In addition, we observed that STK11 modulate not only the apoptotic pathway induced by Fas engagement, but also FasL-induced JNK and NF- KB, sustaining an upstream role of this kinase in the pathway. In conclusion, our report reveals that STK11 is an important pro-apoptotic modulator of the Fas pathway in particular, and extrinsic pathway in general. Our finding could explain, at least partially, why inactivating mutations of the kinase leads to cancer, by allowing resistance to apoptosis and accordingly evasion of immune surveillance. Résumé : L'apoptose est un mécanisme de suicide cellulaire, conservé dans diverses espèces, et qui au niveau moléculaire est déclenché par différentes voies de signalisation, comme par exemple lors de l'activation du récepteur Fas. La liaison du ligand FasL au récepteur de la mort Fas, induit une cascade de signalisation qui conduit à l'activation des caspases. Les lymphocytes Τ cytotoxiques peuvent utiliser la voie Fas pour induire la mort et se débarrasser de cellules dangereuses pour le reste de l'organisme, tel que les cellules transformées. La dysrégulation de l'apoptose en général, et de la voie Fas en particulier, peut contribuer à diverses maladies telles que le cancer. Même si ces dernières décennies, les mécanismes moléculaires conduisant à l'apoptose ont été extensivement étudiés, il reste néanmoins important de mieux comprendre le phénomène d'apoptose, pour améliorer notre compréhension des processus pathologiques, mais surtout dans le but de développer de nouvelles thérapies ciblant l'apoptose contre le cancer et d'autres pathologies. Pour identifier de nouveau constituants de la voie Fas, un criblage génétique basé sur l'interférence à l'ARN a été entrepris. Après un premier et un deuxième criblage d'une librairie du kinome, nous avons identifié différentes protéines qui pourraient jouer un rôle positif dans la voie Fas, et en particulier la protéine suppresseur de tumeur STK11, qui est fréquemment mutée dans divers cancers sporadiques et héréditaires. La caractérisation fonctionnelle de STK11 a révélé que cette kinase était un modulateur apical de la voie extrinsèque de l'apoptose en général (Fas, TNF, TRAIL), mais pas de la voie intrinsèque. L'action de STK11 sur la voie Fas est dépendante de sa fonction kinase, mais indépendante de l'AMPK, un substrat bien caractérisé de STK11. De plus, STK11 interagît avec la caspase-8, un constituant majeur de la voie Fas, et module son activité, par un mécanisme encore peu clair qui pourrait impliquer une phosphorylation de la caspase-8 par STK11. Cette modification pourrait permettre une activation optimale de la caspase-8 en jouant un rôle dans le processus de polyubiquitination de la caspase-8, phénomène qui semble être important pour l'activation de la caspase-8 dans des agrégats protéiques avec p62, mais qui pourrait aussi augmenter son activation au niveau du DISC. Finalement, nous avons observé que STK11 modulait non seulement la voie apoptotique déclenchée par l'activation de Fas, mais aussi les voies non-apoptotiques de Fas, comme JNK et NF-KB. En conclusion notre étude, révèle que STK11 est un important modulateur pro- apoptotique de la voie Fas, et de la voie extrinsèque en général. Cette découverte pourrait expliquer, du moins partiellement, pourquoi les mutations inactivatrices de STK11 conduisent au cancer, par une augmentation de la résistance à l'apoptose et donc par l'évasion de la surveillance immunitaire.

Genome-wide screen of genes required for caffeine tolerance in fission yeast

Background: An excess of caffeine is cytotoxic to all eukaryotic cell types. We aim to study how cells become tolerant to atoxic dose of this drug, and the relationship between caffeine and oxidative stress pathways.Methodology/Principal Findings: We searched for Schizosaccharomyces pombe mutants with inhibited growth on caffeinecontainingplates. We screened a collection of 2,700 haploid mutant cells, of which 98 were sensitive to caffeine. The genes mutated in these sensitive clones were involved in a number of cellular roles including the H2O2-induced Pap1 and Sty1 stress pathways, the integrity and calcineurin pathways, cell morphology and chromatin remodeling. We have investigated the role of the oxidative stress pathways in sensing and promoting survival to caffeine. The Pap1 and the Sty1 pathways are both required for normal tolerance to caffeine, but only the Sty1 pathway is activated by the drug. Cells lacking Pap1 aresensitive to caffeine due to the decreased expression of the efflux pump Hba2. Indeed, ?hba2 cells are sensitive to caffeine, and constitutive activation of the Pap1 pathway enhances resistance to caffeine in an Hba2-dependent manner. Conclusions/Significance: With our caffeine-sensitive, genome-wide screen of an S. pombe deletion collection, we havedemonstrated the importance of some oxidative stress pathway components on wild-type tolerance to the drug.

A sensitized RNA interference screen identifies a novel role for the PI3K p110γ isoform in medulloblastoma cell proliferation and chemoresistance.

Medulloblastoma is the most common malignant brain tumor in children and is associated with a poor outcome. We were interested in gaining further insight into the potential of targeting the human kinome as a novel approach to sensitize medulloblastoma to chemotherapeutic agents. A library of small interfering RNA (siRNA) was used to downregulate the known human protein and lipid kinases in medulloblastoma cell lines. The analysis of cell proliferation, in the presence or absence of a low dose of cisplatin after siRNA transfection, identified new protein and lipid kinases involved in medulloblastoma chemoresistance. PLK1 (polo-like kinase 1) was identified as a kinase involved in proliferation in medulloblastoma cell lines. Moreover, a set of 6 genes comprising ATR, LYK5, MPP2, PIK3CG, PIK4CA, and WNK4 were identified as contributing to both cell proliferation and resistance to cisplatin treatment in medulloblastoma cells. An analysis of the expression of the 6 target genes in primary medulloblastoma tumor samples and cell lines revealed overexpression of LYK5 and PIK3CG. The results of the siRNA screen were validated by target inhibition with specific pharmacological inhibitors. A pharmacological inhibitor of p110γ (encoded by PIK3CG) impaired cell proliferation in medulloblastoma cell lines and sensitized the cells to cisplatin treatment. Together, our data show that the p110γ phosphoinositide 3-kinase isoform is a novel target for combinatorial therapies in medulloblastoma.

International variation in management of screen-detected ductal carcinoma in situ of the breast.

BACKGROUND: Ductal carcinoma in situ (DCIS) incidence has grown with the implementation of screening and its detection varies across International Cancer Screening Network (ICSN) countries. The aim of this survey is to describe the management of screen-detected DCIS in ICSN countries and to evaluate the potential for treatment related morbidity. METHODS: We sought screen-detected DCIS data from the ICSN countries identified during 2004-2008. We adopted standardised data collection forms and analysis and explored DCIS diagnosis and treatment processes ranging from pre-operative diagnosis to type of surgery and radiotherapy. RESULTS: Twelve countries contributed data from a total of 15 screening programmes, all from Europe except the United States of America and Japan. Among women aged 50-69years, 7,176,050 screening tests and 5324 screen-detected DCIS were reported. From 21% to 93% of DCIS had a pre-operative diagnosis (PO); 67-90% of DCIS received breast conservation surgery (BCS), and in 41-100% of the cases this was followed by radiotherapy; 6.4-59% received sentinel lymph node biopsy (SLNB) only and 0.8-49% axillary dissection (ALND) with 0.6% (range by programmes 0-8.1%) being node positive. Among BCS patients 35% received SLNB only and 4.8% received ALND. Starting in 2006, PO and SLNB use increased while ALND remained stable. SLNB and ALND were associated with larger size and higher grade DCIS lesions. CONCLUSIONS: Variation in DCIS management among screened women is wide and includes lymph node surgery beyond what is currently recommended. This indicates the presence of varying levels of overtreatment and the potential for its reduction.

Policy Making in Divided Government. A Pivotal Actors Model with Party Discipline.

This article presents a formal model of policy decision-making in an institutional framework of separation of powers in which the main actors are pivotal political parties with voting discipline. The basic model previously developed from pivotal politics theory for the analysis of the United States lawmaking is here modified to account for policy outcomes and institutional performances in other presidential regimes, especially in Latin America. Legislators' party indiscipline at voting and multi-partism appear as favorable conditions to reduce the size of the equilibrium set containing collectively inefficient outcomes, while a two-party system with strong party discipline is most prone to produce 'gridlock', that is, stability of socially inefficient policies. The article provides a framework for analysis which can induce significant revisions of empirical data, especially regarding the effects of situations of (newly defined) unified and divided government, different decision rules, the number of parties and their discipline. These implications should be testable and may inspire future analytical and empirical work.
