Integration of Standardized Management Systems: A Dilemma?

Abstract: The growing proliferation of management systems standards (MSSs), and their individualized implementation, is a real problem faced by organizations. On the other hand, MSSs are aimed at improving efficiency and effectiveness of organizational responses in order to satisfy the requirements, needs and expectations of the stakeholders. Each organization has its own identity and this is an issue that cannot be neglected; hence, two possible approaches can be attended. First, continue with the implementation of individualized management systems (MSs); or, integrate the several MSSs versus related MSs into an integrated management system (IMS). Therefore, in this context, organizations are faced with a dilemma, as a result of the increasing proliferation and diversity of MSSs. This paper takes into account the knowledge gained through a case study conducted in the context of a Portuguese company and unveils some of the advantages and disadvantages of integration. A methodology is also proposed and presented to support organizations in developing and structuring the integration process of their individualized MSs, and consequently minimize problems that are generators of inefficiencies, value destruction and loss of competitiveness. The obtained results provide relevant information that can support Top Management decision in solving that dilemma and consequently promote a successful integration, including a better control of business risks associated to MSSs requirements and enhancing sustainable performance, considering the context in which organizations operate.

Standard commercial education robotic platform: intermediate solution to teaching robotics

Teaching robotics to students at the beginning of their studies has become a huge challenge. Simulation environments can be an effective solution to that challenge where students can interact with simulated robots and have the first contact with robotic constraints. From our previous experience with simulation environments it was possible to observe that students with lower background knowledge in robotics where able to deal with a limited number of constraints, implement a simulated robotic platform and study several sensors. The question is: after this first phase what should be the best approach? Should the student start developing their own hardware? Hardware development is a very important part of an engineer's education but it can also be a difficult phase that could lead to discouragement and loss of motivation in some students. Considering the previous constraints and first year engineering students’ high abandonment rate it is important to develop teaching strategies to deal with this problem in a feasible way. The solution that we propose is the integration of a low-cost standard robotic platform WowWee Rovio as an intermediate solution between the simulation phase and the stage where the students can develop their own robots. This approach will allow the students to keep working in robotic areas such as: cooperative behaviour, perception, navigation and data fusion. The propose approach proved to be a motivation step not only for the students but also for the teachers. Students and teachers were able to reach an agreement between the level of demand imposed by the teachers and satisfaction/motivation of the students.

Impact of Black-Scholes assumptions on Delta Hedging

In this work we are going to evaluate the different assumptions used in the Black- Scholes-Merton pricing model, namely log-normality of returns, continuous interest rates, inexistence of dividends and transaction costs, and the consequences of using them to hedge different options in real markets, where they often fail to verify. We are going to conduct a series of tests in simulated underlying price series, where alternatively each assumption will be violated and every option delta hedging profit and loss analysed. Ultimately we will monitor how the aggressiveness of an option payoff causes its hedging to be more vulnerable to profit and loss variations, caused by the referred assumptions.

The retinoid-related orphan receptor RORα promotes keratinocyte differentiation via FOXN1.

RORα is a retinoid-related orphan nuclear receptor that regulates inflammation, lipid metabolism, and cellular differentiation of several non-epithelial tissues. In spite of its high expression in skin epithelium, its functions in this tissue remain unclear. Using gain- and loss-of-function approaches to alter RORα gene expression in human keratinocytes (HKCs), we have found that this transcription factor functions as a regulator of epidermal differentiation. Among the 4 RORα isoforms, RORα4 is prominently expressed by keratinocytes in a manner that increases with differentiation. In contrast, RORα levels are significantly lower in skin squamous cell carcinoma tumors (SCCs) and cell lines. Increasing the levels of RORα4 in HKCs enhanced the expression of structural proteins associated with early and late differentiation, as well as genes involved in lipid barrier formation. Gene silencing of RORα impaired the ability of keratinocytes to differentiate in an in vivo epidermal cyst model. The pro-differentiation function of RORα is mediated at least in part by FOXN1, a well-known pro-differentiation transcription factor that we establish as a novel direct target of RORα in keratinocytes. Our results point to RORα as a novel node in the keratinocyte differentiation network and further suggest that the identification of RORα ligands may prove useful for treating skin disorders that are associated with abnormal keratinocyte differentiation, including cancer.

Extracorporeal membrane oxygenation support after heart explantation: a proposal on how to deal with hyperacute rejection of heart transplant

Purpose: In extreme situations, such as hyperacute rejection of heart transplant or major bleeding per-operating complications, an urgent heart explantation might be the only means of survival. The aim of this experimental study was to improve the surgical technique and the hemodynamics of an Extracorporeal Membrane Oxygenation (ECMO) support through a peripheral vascular access in an acardia model. Methods: An ECMO support was established in 7 bovine experiments (59±6.1 kg) by the transjugular insertion to the caval axis of a self-expanded cannula, with return through a carotid artery. After baseline measurements of pump flow and arterial and central venous pressure, ventricular fibrillation was induced (B), the great arteries were clamped, the heart was excised and right and left atria remnants, containing the pulmonary veins, were sutured together leaving an atrial septal defect (ASD) over the cannula in the caval axis. Measurements were taken with the pulmonary artery (PA) clamped (C) and anastomosed with the caval axis (D). Regular arterial and central venous blood gases tests were performed. The ANOVA test for repeated measures was used to test the null hypothesis and a Bonferroni t method for assessing the significance in the between groups pairwise comparison of mean pump flow. Results: Initial pump flow (A) was 4.3±0.6 L/min dropping to 2.8±0.7 L/min (P B-A= 0.003) 10 minutes after induction of ventricular fibrillation (B). After cardiectomy, with the pulmonary artery clamped (C) it augmented not significantly to 3.5±0.8 L/min (P C-B= 0.33, P C-A= 0.029). Finally, PA anastomosis to the caval axis was followed by an almost to baseline pump flow augmentation (4.1±0.7 L/min, P D-B= 0.009, P D-C= 0.006, P D-A= 0.597), permitting a full ECMO support in acardia by a peripheral vascular access. Conclusions: ECMO support in acardia is feasible, providing new opportunities in situations where heart must urgently be explanted, as in hyperacute rejection of heart transplant. Adequate drainage of pulmonary circulation is pivotal in order to avoid pulmonary congestion and loss of volume from the normal right to left shunt of bronchial vessels. Furthermore, the PA anastomosis to the caval axis not only improves pump flow but it also permits an ECMO support by a peripheral vascular access and the closure of the chest.

Impact of enhanced compliance initiatives on the efficacy of rosuvastatin in reducing low density lipoprotein cholesterol levels in patients with primary hypercholesterolaemia.

The effectiveness of lipid-lowering medication critically depends on the patients' compliance and the efficacy of the prescribed drug. The primary objective of this multicentre study was to compare the efficacy of rosuvastatin with or without access to compliance initiatives, in bringing patients to the Joint European Task Force's (1998) recommended low-density lipoprotein cholesterol (LDL-C) level goal (LDL-C, <3.0 mmol/L) at week 24. Secondary objectives were comparison of the number and percentage of patients achieving European goals (1998, 2003) for LDL-C and other lipid parameters. Patients with primary hypercholesterolaemia and a 10-year coronary heart disease risk of >20% received open label rosuvastatin treatment for 24 weeks with or without access to compliance enhancement tools. The initial daily dosage of 10 mg could be doubled at week 12. Compliance tools included: a) a starter pack for subjects containing a videotape, an educational leaflet, a passport/goal diary and details of the helpline and/or website; b) regular personalised letters to provide message reinforcement; c) a toll-free helpline and a website. The majority of patients (67%) achieved the 1998 European goal for LDL-C at week 24. 31% required an increase in dosage of rosuvastatin to 20 mg at week 12. Compliance enhancement tools did not increase the number of patients achieving either the 1998 or the 2003 European target for plasma lipids. Rosuvastatin was well tolerated during this study. The safety profile was comparable with other drugs of the same class. 63 patients in the 10 mg group and 58 in the 10 mg Plus group discontinued treatment. The main reasons for discontinuation were adverse events (39 patients in the 10 mg group; 35 patients in the 10 mg Plus group) and loss to follow-up (13 patients in the 10 mg group; 9 patients in the 10 mg Plus group). The two most frequently reported adverse events were myalgia (34 patients, 3% respectively) and back pain (23 patients, 2% respectively). The overall rate of temporary or permanent study discontinuation due to adverse events was 9% (n = 101) in patients receiving 10 mg rosuvastatin and 3% (n = 9) in patients titrated up to 20 mg rosuvastatin. Rosuvastatin was effective in lowering LDL-C values in patients with hypercholesterolaemia to the 1998 European target at week 24. However, compliance enhancement tools did not increase the number of patients achieving any European targets for plasma lipids.

Collective learning within nursing clinical groups /

This qualitative study examined collective learning within nursing clinical groups. Specifically, it explored the influence of the individual on the group and the impact of the group on the individual. The study was organized using the concepts from Debbie Kilgore's theory of collective learning (1999). The sample consisted of 1 8 second-year university nursing students and 3 clinical instructors. Data were collected via individual interviews with each participant and researcher's observations during a group conference. The interviews were tape-recorded, transcribed, and analyzed using key concepts from Kilgore's framework. Several interesting findings emerged. Overall, it appeared that individual components and group components contributed to the quality and quantity of collective learning that occurred in the groups. Individually, each person's past group experiences, personality, culture, and gender influenced how that individual acted in the group, their roles, and how much influence they had over group decisions. Moreover, the situation which seemed to cause the greatest sense of helplessness and loss of control was when one of their group members was breaking a norm. They were unable to deal with such situations constructively. Also, the amount of sense of worthiness (respect) and sense of agency (control) the member felt within the group had an impact on the person's role in group decisions. Finally, it seemed that students felt more connected with their peers within the clinical setting when they were close with them on a personal and social level. With respect to the group elements, it seemed that the instructors' values and way of being were instrumental in shaping the group's identity. In group 2, there were clear examples of group consciousness and the students' need to go along with the majority viewpoint, even when it was contrary to their own beliefs. Finally, the common goal of passing clinical and dealing with the fears of being in the clinical setting brought solidarity among the group members, and there seemed to be a high level of positive interdependence among them. From the discussion and analysis of the findings, recommendations were given on how to improve the learning within clinical groups.

Identifying the psychosexual implications of radical radiation treatment in prostate cancer

The purpose of this study was to determine whether there was any evidence of psychosexual morbidity among men who experienced radical radiation treatment for prostate cancer. With relatively little known or available retrospective data on the psychosexual implications of radical radiation treatment in men with prostate cancer, this study posited eight research questions which provided the basis for the research. Fifty men from Southern Ontario, between the ages of 52 to 78 years, were included in the study. They had been previously randomized to a clinical trial comparing radical radiation therapy by external beam radiation, or radical radiation using a combination of a temporary iridium implant plus external beam radiation, for localized or locally advanced prostate cancer. Assessment of sexual functioning, drive, attitudes, body image, and sexual satisfaction was drawn from a multidimensional approach, since psychosexuality was viewed as having an impact on biological, psychological, and sociological domains of functioning. Medical chart reviews, semi-structured interviews, demographical profiles of each participant, and the Derogatis Sexual Functioning Inventory (DSFI) were the methods used to collect data over a four-month period. Both quantitative and qualitative research methods were incorporated in the design and evaluation of the study. Frequencies, contingency analysis, Pearson's coefficient of correlation, t-tests, and ANOVA comprised the quantitative analysis. Data obtained from audio-taped interviews were analyzed qualitatively, and used for offering further insight and for facilitating the quantitative aspect of the analysis. Overall, there was sufficient evidence to suggest psychosexual morbidity among men who were treated with radiation therapy for prostate cancer. As well,there were a number of significant findings available to answer all of the posited research questions. The most significant findings were noted in post-treatment erectile ability and sexual activity. A post-treatment change in erectile ability was reported by eighty percent of men. Sixty percent of men noted a decrease in their ability to achieve an erection by reporting some morning stiffness only, penile rigidity insufficient for penetration, decreased control of erection, and loss of spontaneous erection. Other contributing factors associated with change in erectile status were: pain or altering sensation of orgasm, blood in ejaculate, pain and decreased amount of ejaculate, and penile numbness or pain. Eighty-two percent of men experienced a post-treatment change in sexual function, primarily due to the impact of decreasing erectile status. Only seven men reported that they experienced a decrease in desire mentally, whereas the vast majority did not experience any change in desire. Changes in foreplay, stress with optimal sexual positioning, and reduced spontaneity of sex, were other factors reported with the changes in sexual activity. The findings in this study broaden our understanding of what middle- to later-aged men feel and experience as they venture onward following treatment. This was the first study that evaluated available prospective data on pre-treatment erectile status and sexual activity. As well, this study was the first (with participant compliance rates of 100 percent) to have included an interview format to capture the views of such a large number of men. This study concluded with recommendations and implications for future research and practice as we move in the direction of understanding what is necessary for preserving psychosexual well being and enhancing quality of life in men treated with radiation therapy for prostate cancer.

Src family kinases are required for limb trajectory selection by spinal motor axons

Signal relay by guidance receptors at the axonal growth cone is a process essential for the assembly of a functional nervous system. We investigated the in vivo function of Src family kinases (SFKs) as growth cone guidance signaling intermediates in the context of spinal lateral motor column (LMC) motor axon projection toward the ventral or dorsal limb mesenchyme. Using in situ mRNA detection we determined that Src and Fyn are expressed in LMC motor neurons of chick and mouse embryos at the time of limb trajectory selection. Inhibition of SFK activity by C-terminal Src kinase (Csk) overexpression in chickLMCaxons using in ovo electroporation resulted inLMC axons selecting the inappropriate dorsoventral trajectory within the limb mesenchyme, with medial LMC axon projecting into the dorsal and ventral limb nerve with apparently random incidence. We also detected LMC axon trajectory choice errors in Src mutant mice demonstrating a nonredundant role for Src in motor axon guidance in agreement with gain and loss of Src function in chickLMCneurons which led to the redirection ofLMCaxons. Finally, Csk-mediated SFK inhibition attenuated the retargeting ofLMCaxons caused by EphA or EphB over-expression, implying the participation of SFKs in Eph-mediated LMC motor axon guidance. In summary, our findings demonstrate that SFKs are essential for motor axon guidance and suggest that they play an important role in relaying ephrin:Eph signals that mediate the selection of motor axon trajectory in the limb.

Étude du dysfonctionnement du compartiment des cellules B chez des patients à différents stades d’infection par le virus d’immunodéficience humaine (VIH)

Les anomalies phénotypiques et fonctionnelles des lymphocytes B (LB) sont typiques d'une infection au VIH et se traduisent principalement par une activation polyclonale, une perte de la mémoire immunitaire ainsi qu'une réponse humorale déficiente et des phénomènes auto-immunitaires souvent précurseurs de lymphomes B. Ces anomalies se retrouvent principalement chez les patients lors de la phase chronique de la maladie et semblent être reliées en partie au niveau de la charge virale ainsi qu'à un compartiment de lymphocytes T CD4+ altéré. Cependant, quoique controversé, des éléments d’activation polyclonale ont également été observés chez les non-progresseurs à long terme (LTNPs) qui présentent une charge virale faible et un compartiment T CD4+ semblable aux individus séronégatifs. Ainsi, les objectifs principaux de cette étude sont 1) d’établir une chronologie des anomalies du compartiment des cellules B chez des individus infectés par le VIH qui ont une progression différente de la maladie (PHI normaux, rapides, sains et LTNP). 2) corréler les niveaux sériques du stimulateur de lymphocytes B (BLyS), un facteur de croissance des cellules B, avec les phénotypes observés chez ces mêmes patients. L’hyperglobulinémie, les niveaux sériques de BLyS et d’auto-anticorps ont été mesuré longitudinalement chez une cohorte d’individus en primo-infection (PHI) avec des progressions différentes de la maladie (rapides et normaux), LTNP et sujets sains. Nos résultats démontrent que l’activation polyclonale des LB survient indépendamment de la vitesse de progression et persiste chez les LTNP ou malgré une thérapie antirétrovirale efficace chez les progresseurs rapides. Des niveaux élevés de BLyS dans le sérum des progresseurs rapides corrèlent avec des fréquences altérées de monocytes et cellules dendritiques, suggérant un rôle de celles-ci dans l’atteinte du compartiment des cellules B.

Abus sexuels et conversion religieuse : une approche narrative fondée sur la triple mimèsis de Paul Ricœur

Bien qu’on ait longtemps considéré le désespoir ou la souffrance comme un facteur de précipitation de l’expérience religieuse, aucune étude n’a été effectuée sur les liens entre une expérience d’abus sexuels et une conversion religieuse subséquente. Une revue de la littérature sur la dynamique religieuse des abus sexuels révèle deux paradigmes opposés : la religion comme ressource ou comme facteur de risque. De même, un examen des études sur la conversion indique trois dichotomies : un converti actif ou passif, une conversion soudaine ou progressive, et la conversion comme phénomène normal ou pathologique. Or, un recensement des témoignages anecdotiques de victimes d’abus sexuels qui ont subséquemment vécu une conversion suggère que l'interaction entre les deux événements est plus complexe. Pour dépasser ces dichotomies paradigmatiques, nous préconisons une approche narrative. Plus spécifiquement, nous utilisons le concept d’identité narrative développé par Paul Ricœur. Ce concept s’inscrit dans la dynamique ricœurienne de triple mimèsis, laquelle assure une fonction de liaison entre le champ pratique et le champ narratif. De façon générale, notre stratégie méthodologique consiste à déterminer comment, à partir d’éléments biographiques issus de la préfiguration (mimèsis I), le sujet configure son récit pour donner sens à son expérience (mimèsis II) et la refigure pour aboutir à une identité de survivant ou de converti (mimèsis III). Sept entrevues non directives ont été effectuées auprès de personnes qui ont subi des abus sexuels durant leur enfance et qui ont plus tard vécu une conversion religieuse dans le milieu évangélique. À partir de l'analyse en trois étapes mentionnée ci-dessus, nous évaluons la contribution positive ou négative des divers éléments narratifs et, surtout, de leur interaction à la construction de l’identité narrative du sujet. Nous en concluons que le rapport entre des abus sexuels subis durant l’enfance et une conversion ultérieure n’est pas si simple que la littérature pourrait le laisser soupçonner. La conversion peut s’avérer salutaire à la survie du sujet et contribuer à la guérison du traumatisme sexuel qu’il a subi. Toutefois, certains éléments religieux peuvent faire obstacle au processus de recouvrement. Ces éléments nocifs varient d’un sujet à l’autre, et ce qui est délétère pour l’un peut être bénéfique pour l’autre, selon la configuration du récit.

Les sens des cris de personnes âgées vivant avec une démence en centre d’hébergement et de soins de longue durée

Dans les centres d’hébergement et de soins de longue durée (CHSLD), jusqu’à 80 % des personnes admises vivent avec une démence (Conseil des aînés, 2007). Parmi ces personnes âgées, plusieurs crient. Ce comportement a fait l’objet de quelques études, mais ces études ne fournissent pas une compréhension des sens de ces cris qui pourrait orienter le choix d’interventions face à ces personnes et leur entourage. À l’aide de la perspective infirmière de Leininger (2001) et de la théorie de la communication et des interactions à l’intérieur de triades d’Adams et Gardiner (2005), le but de cette étude était de décrire les sens des cris de personnes âgées vivant avec une démence et les facteurs les influençant en tenant compte de la perspective des personnes âgées, de leurs aidants familiaux et de leurs soignants. Pour atteindre ce but, l’ethnographie critique a été choisie comme méthode. L’étude s’est découlée dans un CHSLD au sein duquel sept triades, composées de personnes âgées vivant avec une démence qui crient, d’aidants familiaux principaux et de soignants, ont été recrutées selon un échantillonnage théorique. Diverses méthodes de collecte des données ont été utilisées dont l’observation des personnes âgées et du milieu et des entrevues semi-dirigées auprès des aidants et soignants. L’analyse des données a été effectuée à l’aide des quatre approches proposées par Spradley (1979) soit l’analyse : des domaines, taxonomique, componentielle et thématique. Les résultats ont permis d’identifier des thèmes sur les sens des cris et sur les facteurs influençant ceux-ci. Les cris peuvent avoir pour sens la vulnérabilité, la souffrance et la perte de sens vécues par la personne âgée. Ce comportement peut aussi indiquer diverses finalités, par exemple l’expression d’insatisfactions ou d’émotions. Ces finalités peuvent être distinguées à partir de critères de modulation tels que la prévisibilité des cris ou un faciès émotif. Par ailleurs, divers aspects rendent les sens des cris singuliers. La stabilité et la flexibilité dans la façon d’organiser les soins ainsi que l’effet réciproque entre les personnes âgées qui crient et les autres personnes dans le CHSLD se sont dégagées comme étant des facteurs qui influencent les sens des cris. Il s’est aussi révélé que les cris de chaque personne âgée peuvent être considérés comme un langage unique que les aidants et les soignants sont en mesure d’apprendre et qui influence l’interprétation des sens des cris. L’accompagnement de la personne âgée, en tenant compte de ses volontés, ses besoins et de sa personnalité, les fluctuations dans les relations de pouvoir au sein des triades personnes âgées-aidants-soignants et les sentiments d’impuissance et de culpabilité des aidants et des soignants sont d’autres facteurs qui influencent les cris. Les connaissances découlant de cette étude augmentent la compréhension sur les sens des cris des personnes âgées vivant avec une démence. Elles ont des implications pour les divers champs d’activités des infirmières et qui pourront contribuer à offrir des soins culturellement cohérents et caring pour les personnes âgées vivant avec une démence et leur entourage.
