OBJECTIVES: To describe the diagnostic performance of a new fourth-generation HIV Ag/Ab chemiluminescent immunoassay, available on the new LIAISON® XL analyser, in a clinical setting. METHODS: Through February 2012-October 2013, 12,438 samples of serum, received at our laboratory for screening for HIV infection were routinely tested with LIAISON® XL Murex HIV Ab/Ag assay (HIV-XL), which employs HIV-1, HIV-1 group O, and HIV-2 antigens and anti-p24 monoclonal antibodies in two coupled reagent cartridges, providing information of the overall Ab/Ag reactivity and detail of the specific reactivity for anti-HIV/HIV p24 antigen. Each serum with positive result or with negative result displaying a value close to the cut-off were sent to the regional AIDS-Reference Laboratory (RefLab) to perform confirmatory assays (PCR, Immunoblot). A previous verification of the HIV-XL demonstrated 100% sensitivity with a challenge panel of hundred positive sera provided by the RefLab. Performed external quality control was from United-Kingdom National External Quality Assessment Service (NEQAS). RESULTS: Out of the clinical samples, 12,312 non-reactive samples (including 6 negative results displaying a value close to the cut-off further confirmed true HIV negative), 64 Ab HIV reactive samples (all confirmed HIV-1 positive by immunoblot), including 4 samples reactive also for Ag HIV (confirmed positive by Ag assay/PCR), 42 Ab HIV reactive samples tested negative by immunoblot, and 20 Ag HIV reactive samples tested negative by the kit used for the Ag p24 detection in our HIV Reference Lab, have been found. All the 43 NEQAS specimens tested, 16 reactive and 27 non-reactive, were correctly classified. These results, considered all together, provide a calculated positive predictive value of 57.5% with an estimated specificity of 99.5% (with 95% confidence interval of 99.36-99.62%), and a calculated negative predictive value of 100% with an estimated sensitivity of 100.0% (with 95% confidence interval of 95.49-100%). CONCLUSIONS: In our experience HIV-XL showed excellent performance associated to all the advantages of a fully automated/random access instrument. [less ▲]

ABSTRACT We examined the relationships between perceived outplacement adequacy, retrospective justice and outplacement benefits for redundant employees using outplacement services. Based on an outplacement experience perceived as adequate, victims formed retrospective justice perceptions about their former organization that in turn, impacted their negative emotions, well-being, future perspectives and job search. PRESS PARAGRAPH The increasing prevalence of organizational downsizing has been matched by growth in the provision of outplacement services over the last decade. Despite this rapid growth and ongoing need for outplacement services, little is yet known about the perceived adequacy and the benefits of these services for redundant employees using them. Our results indicated that an outplacement experience perceived as adequate for redundant employees retrospectively fosters their impressions of justice about the dismissing organization; this leads in turn to satisfactory benefits for them: reduction of negative emotions, enhancement of their perceived well-being, future perspectives, and job-seeking activities.

ABSTRACT This study aimed to examine the directionality of the relationship between event justice and social entity justice. Using two samples and a cross-lagged panel analysis with two measurement times, social entity justice was found to predict event justice (procedural, distributive, interpersonal and informational justice event), supporting the top-down process. PRESS PARAGRAPH The life of organizations is punctuated by a wide range of managerial decisions (e.g., hiring, performance appraisal or organizational change). Facing such events, employees evaluate the fairness of the situation experienced. However, little is known about how employees develop justice judgments. This study shows that employees’ fairness perceptions about their organization influence their interpretation of the fairness of subsequent events involving the organization. Building and fostering a climate of justice is therefore of primary importance for organizations, since global fairness perceptions about the organization may help employees to perceive a specific event, such as a managerial decision, as being fair.

Michard (2009) nous dit de la loyauté qu’elle est l’armature de l’appartenance et à Neuburger de souligner qu’en plus d’être un socle sur lequel l’identité se structure, l’appartenance contient et limite les effets des relations (2003). Pour Onnis (2008) c’est dans la dialectique entre identité et appartenance que naît l’individualité qui, elle, se réalise dans la relation (Dolto, 1988). Plymackers (2006) insiste sur les notions d’espaces où se nouent ces relations mais aussi de temps où ces dernières se jouent. L’enfant, par des mouvements dialectiques d’allées et venues avec son/ses système(s) d’appartenances tisse pas à pas les prémices de son identité. Ses relations structurent et étayent ce processus et la temporalité constitue le squelette de celui-ci. Mais qu’en est-il de ces enfants placés, maltraités, déplacés ? Qu’en est-il si le conflit ou le clivage de loyauté entre famille(s) et institution(s) rend l’étayage de l’appartenance ardu ? Qu’en est-il si la discontinuité des espaces et des relations prédomine et si le processus d’individuation est suspendu par une séparation arbitraire dictée par un autrui qui « n’appartient pas » ? L’analyse clinique de cas d’enfants aux vécus chaotiques rythmés par de nombreux placements nous permet de décortiquer les particularités de ce processus complexifié par ces ruptures d’espaces, ces loyautés morcelées, ces appartenances diffuses et d’en cerner les impacts.

Among evolved massive stars likely in transition to the Wolf-Rayet phase, IRC +10420 is probably one of the most enigmatic. It belongs to the category of yellow hypergiants and it is characterized by quite high mass loss episodes. Even though IRC+10420 benefited of many observations in several wavelength domains, it has never been a target for an X-ray observatory. We report here on the very first dedicated observation of IRC+10420 in X-rays, using the XMM-Newton satellite. Even though the target is not detected, we derive X-ray flux upper limits of the order of 1–3 ×10−14 erg cm−2 s−1 (between 0.3 and 10.0 keV), and we discuss the case of IRC+10420 in the framework of emission models likely to be adequate for such an object. Using the Optical/UV Monitor on board XMM-Newton, we present the very first upper limits of the flux density of IRC +10420 in the UV domain (between 1800 and 2250 Å and between 2050 and 2450 Å). Finally, we also report on the detection in this field of 10 X-ray and 7 UV point sources, and we briefly discuss their properties and potential counterparts at longer wavelengths. [less ▲]

We present a novel methodology combining web-based software development practices, machine learning, and spatial databases for computer-aided quantification of regions of interest (ROIs) in large-scale imaging data. We describe our main methodological choices, and then illustrate the benefits of the approach (workload reduction, improved precision, scalability, and traceability) on hundreds of whole-slide images of biological tissue slices in cancer research.
