Bridging the gap with teamwork: collaborative leadership for communities of practice in the learning and skills sector

Collaborative approaches in leadership and management are increasingly acknowledged to play a key role in successful institutions in the learning and skills sector (LSS) (Ofsted, 2004). Such approaches may be important in bridging the potential 'distance' (psychological, cultural, interactional and geographical) (Collinson, 2005) that may exist between 'leaders' and 'followers', fostering more democratic communal solidarity. This paper reports on a 2006-07 research project funded by the Centre for Excellence in Leadership (CEL) that aimed to collect and analyse data on 'collaborative leadership' (CL) in the learning and skills sector. The project investigated collaborative leadership and its potential for benefiting staff through trust and knowledge-sharing in communities of practice (CoPs). The project forms part of longer-term educational research investigating leadership in a collaborative inquiry process (Jameson et al., 2006). The research examined the potential for CL to benefit institutions, analysing respondents' understanding of and resistance to collaborative practices. Quantitative and qualitative data from senior managers and lecturers was analysed using electronic data in SPSS and Tropes Zoom. The project aimed to recommend systems and practices for more inclusive, diverse leadership (Lumby et al., 2005). Collaborative leadership has increasingly gained international prominence as emphasis shifted towards team leadership beyond zero-sum 'leadership'/ 'followership' polarities into more mature conceptions of shared leadership spaces, within which synergistic leadership spaces can be mediated. The relevance of collaboration within the LSS has been highlighted following a spate of recent government-driven policy developments in FE. The promotion of CL addresses concerns about the apparent 'remoteness' of some senior managers, and the 'neo-management' control of professionals which can increase 'distance' between leaders and 'followers' and may de-professionalise staff in an already disempowered sector. Positive benefit from 'collaborative advantage' tends to be assumed in idealistic interpretations of CL, but potential 'collaborative inertia' may be problematic in a sector characterised by rapid top-down policy changes and continuous external audit and surveillance. Constant pressure for achievement against goals leaves little time for democratic group negotiations, despite the desires of leaders to create a more collaborative ethos. Yet prior models of intentional communities of practice potentially offer promise for CL practice to improve group performance despite multiple constraints. The CAMEL CoP model (JISC infoNet, 2006) was linked to the project, providing one practical way of implementing CL within situated professional networks.The project found that a good understanding of CL was demonstrated by most respondents, who thought it could enable staff to share power and work in partnership to build trust and conjoin skills, abilities and experience to achieve common goals for the good of the sector. However, although most respondents expressed agreement with the concept and ideals of CL, many thought this was currently an idealistically democratic, unachievable pipe dream in the LSS. Many respondents expressed concerns with the 'audit culture' and authoritarian management structures in FE. While there was a strong desire to see greater levels of implementation of CL, and 'collaborative advantage' from the 'knowledge sharing benefit potential' of team leadership, respondents also strongly advised against the pitfalls of 'collaborative inertia'. A 'distance' between senior leadership views and those of staff lower down the hierarchy regarding aspects of leadership performance in the sector was reported. Finally, the project found that more research is needed to investigate CL and develop innovative methods of practical implementation within autonomous communities of professional practice.

Polycyclic aromatic hydrocarbons (PAHS) (I): Toxicity, population exposure and involved foods

Food is one of the main exogenous sources of genotoxic compounds. In heated food products, polycyclic aromatic hydrocarbons (PAHs) represent a priority group of genotoxic, mutagenic and/or carcinogenic chemical pollutants with adverse long-term health effects. People can be exposed to these compounds through different environments and via various routes: inhalation, ingestion of foods and water and even percutaneously. The presence of these compounds in food may be due to environmental contamination, to industrial handling and processing of foods and to oil processing and refining. The highest levels of these compounds are found in smoked foods, in seafood which is found in polluted waters, in grilled meats and, to a lesser extent, in vegetable fats and oils. Lower levels of PAHs are found in vegetables and in cereals and its products.

Levels of glucose and triglycerides in seminal plasma and spermatic motility in guinea pig fed with 10% more in digestible energy

The objective the study was to determine the levels of glucose and triglycerides in seminal plasma of 10 guinea pigs, which were fed for a period of 2 months with a diet containing 10% more ED. The level of glucose found in seminal plasma was 11.59 ± 0.5 mg/dL and triglyceride value was 55.95 ± 3.2 mg/dL, while the motility was 97% on average. We conclude that in guinea pigs the levels both glucose and triglycerides were increased by major level of ED in feed, but the spermatic motility was not.

Sensing Spaces:A Body-oriented Architectural Design Education

The contemporary dominance of visuality has turned our understanding of space into a mode of unidirectional experience that externalizes other sensual capacities of the body while perceiving the built environment. This affects not only architectural practice but also architectural education when an introduction to the concept of space is often challenging, especially for the students who have limited spatial and sensual training. Considering that an architectural work is not perceived as a series of retinal pictures but as a repeated multi-sensory experience, the problem definitions in the design studio need to be disengaged from the dominance of a ‘focused vision’ and be re-constructed in a holistic manner. A method to address this approach is to enable the students to refer to their own sensual experiences of the built environment as a part of their design processes. This paper focuses on a particular approach to the second year architectural design teaching which has been followed in the Department of Architecture at Izmir University of Economics for the last three years. The very first architectural project of the studio and the program, entitled ‘Sensing Spaces’, is conducted as a multi-staged design process including ‘sense games, analyses of organs and their interpretations into space’. The objectives of this four-week project are to explore the sense of space through the design of a three-dimensional assembly, to create an awareness of the significance of the senses in the design process and to experiment with re-interpreted forms of bodily parts. Hence, the students are encouraged to explore architectural space through their ‘tactile, olfactory, auditory, gustative and visual stimuli’. In this paper, based on a series of examples, architectural space is examined beyond its boundaries of structure, form and function, and spatial design is considered as an activity of re-constructing the built environment through the awareness of bodily senses.

An Impact Of Various Shroud Bleed Slot Configurations And Cavity Vanes On Compressor Map Width And The Inducer Flow Field

This paper describes an investigation of map width enhancement and a detailed analysis of the inducer flow field due to various bleed slot configurations and vanes in the annular cavity of a turbocharger centrifugal compressor. The compressor under investigation is used in a turbocharger application for a heavy duty diesel engine of approximately 400 hp. This investigation has been undertaken using a computational fluid dynamics (CFD) model of the full compressor stage, which includes a manual multiblock-structured grid generation method. The influence of the bleed slot flow on the inducer flow field at a range of operating conditions has been analyzed, highlighting the improvement in surge and choked flow capability. The impact of the bleed slot geometry variations and the inclusion of cavity vanes on the inlet incidence angle have been studied in detail by considering the swirl component introduced at the leading edge by the recirculating flow through the slot. Further, the overall stage efficiency and the nonuniform flow field at the inducer inlet have been also analyzed. The analysis revealed that increasing the slot width has increased the map width by about 17%. However, it has a small impact on the efficiency, due to the frictional and mixing losses. Moreover, adding vanes in the cavity improved the pressure ratio and compressor performance noticeably. A detail analysis of the compressor with cavity vanes has also been presented.

Urban Oasis:Ajman as Event City

The Urban Oasis celebrates Ajman’s history as well as encourages a greater future. Stitching into the existing urban fabric of Ajman and the surrounding cities, the master plan provides an entrance that encases a number of different events. From studying other successful event cities, it became apparent the need for a variety of events over a yearly basis.

Sustainability is another key feature of the master plan. From the way the urban network of streets are formed and orientated to how energy is produced and conserved. Another sustainable aspect that drove the master plan was the retention of the camel track. An important and incredible event in itself, the camel track provides an opportunity to celebrate Ajman’s culture and retain an important part of its history.

The seasons of Zarathustra and their correspondence to the metamorphoses of the spirit

Nietzsche employed metaphors frequently throughout his works. This is especially true in Thus Spoke Zarathustra. Although this is often aesthetically pleasing, it can be very difficult for the reader to understand the nuances and interconnections with the various metaphors. This is generally considered one of the main drawbacks of Thus Spoke Zarathustra. While it is beautifully written in a style that is incomparable today, much of what it is attempting to communicate is lost on the reader. This thesis explores the connection between the metamorphoses of the spirit and the seasons in Thus'Spoke Zarathustra, with the camel spirit corresponding to autumn, the lion spirit with winter, the child spirit with spring, and finally the Overman with summer. Although the Overman is not included among the three metamorphoses of the spirit, it will be argued that the Overman is a separate metamorphosis and must not be conflated with the child spirit despite their similarities. While Thus Spoke Zarathustra will be the primary text used, Nietzsche's other works will be employed to demonstrate that this connection between the metamorphoses of the spirit and the seasons runs through much of his thought. By demonstrating how the seasons are used in Thus Spoke Zarathustra, a deeper understanding of the work will be revealed. Further, this thesis will demonstrate that it is an intentional connection, and not merely coincidental or something that has been constructed and imposed upon the work. Bringing this correspondence between the metamorphoses of the spirit and the seasons to light will result in the need to rethink particular notions of Nietzsche's philosophy. The most apparent involves the Overman and the process of overcoming. Although the Overman has often been viewed as "the end" in the cycle of metamorphoses, it will be argued that this is not the case. The typical interpretation of the metamorphoses of the spirit regard it as a linear progression; however, it will be shown that the metamorphoses of the spirit is cyclical with the camel, lion, and child spirits endlessly repeating, much like the seasons.

Cell lines and animal model in the analysis of pharmacogenomics markers in childhood acute lymphoblastic leukemia

La leucémie aiguë lymphoblastique (LAL) est le cancer pédiatrique le plus fréquent. Elle est la cause principale de mortalité liée au cancer chez les enfants due à un groupe de patient ne répondant pas au traitement. Les patients peuvent aussi souffrir de plusieurs toxicités associées à un traitement intensif de chimiothérapie. Les études en pharmacogénétique de notre groupe ont montré une corrélation tant individuelle que combinée entre les variants génétiques particuliers d’enzymes dépendantes du folate, particulièrement la dihydrofolate réductase (DHFR) ainsi que la thymidylate synthase (TS), principales cibles du méthotrexate (MTX) et le risque élevé de rechute chez les patients atteints de la LAL. En outre, des variations dans le gène ATF5 impliqué dans la régulation de l’asparagine synthetase (ASNS) sont associées à un risque plus élevé de rechute ou à une toxicité ASNase dépendante chez les patients ayant reçu de l’asparaginase d’E.coli (ASNase). Le but principal de mon projet de thèse est de comprendre davantage d’un point de vue fonctionnel, le rôle de variations génétiques dans la réponse thérapeutique chez les patients atteints de la LAL, en se concentrant sur deux composants majeurs du traitement de la LAL soit le MTX ainsi que l’ASNase. Mon objectif spécifique était d’analyser une association trouvée dans des paramètres cliniques par le biais d’essais de prolifération cellulaire de lignées cellulaires lymphoblastoïdes (LCLs, n=93) et d’un modèle murin de xénogreffe de la LAL. Une variation génétique dans le polymorphisme TS (homozygosité de l’allèle de la répétition triple 3R) ainsi que l’haplotype *1b de DHFR (défini par une combinaison particulière d’allèle dérivé de six sites polymorphiques dans le promoteur majeur et mineur de DHFR) et de leurs effets sur la sensibilité au MTX ont été évalués par le biais d’essais de prolifération cellulaire. Des essais in vitro similaires sur la réponse à l’ASNase de E. Coli ont permis d’évaluer l’effet de la variation T1562C de la région 5’UTR de ATF5 ainsi que des haplotypes particuliers du gène ASNS (définis par deux variations génétiques et arbitrairement appelés haplotype *1). Le modèle murin de xénogreffe ont été utilisé pour évaluer l’effet du génotype 3R3R du gène TS. L’analyse de polymorphismes additionnels dans le gène ASNS a révélé une diversification de l’haplotype *1 en 5 sous-types définis par deux polymorphismes (rs10486009 et rs6971012,) et corrélé avec la sensibilité in vitro à l’ASNase et l’un d’eux (rs10486009) semble particulièrement important dans la réduction de la sensibilité in vitro à l’ASNase, pouvant expliquer une sensibilité réduite de l’haplotype *1 dans des paramètres cliniques. Aucune association entre ATF5 T1562C et des essais de prolifération cellulaire en réponse à ASNase de E.Coli n’a été détectée. Nous n’avons pas détecté une association liée au génotype lors d’analyse in vitro de sensibilité au MTX. Par contre, des résultats in vivo issus de modèle murin de xénogreffe ont montré une relation entre le génotype TS 3R/3R et la résistance de manière dose-dépendante au traitement par MTX. Les résultats obtenus ont permis de fournir une explication concernant un haut risque significatif de rechute rencontré chez les patients au génotype TS 3R/3R et suggèrent que ces patients pourraient recevoir une augmentation de leur dose de MTX. À travers ces expériences, nous avons aussi démontré que les modèles murins de xénogreffe peuvent servir comme outil préclinique afin d’explorer l’option d’un traitement individualisé. En conclusion, la connaissance acquise à travers mon projet de thèse a permis de confirmer et/ou d’identifier quelques variants dans la voix d’action du MTX et de l’ASNase qui pourraient faciliter la mise en place de stratégies d’individualisation de la dose, permettant la sélection d’un traitement optimum ou moduler la thérapie basé sur la génétique individuelle.

PTPN22 Association in Systemic Lupus Erythematosus (SLE) with Respect to Individual Ancestry and Clinical Sub-Phenotypes

Protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a negative regulator of T-cell activation associated with several autoimmune diseases, including systemic lupus erythematosus (SLE). Missense rs2476601 is associated with SLE in individuals with European ancestry. Since the rs2476601 risk allele frequency differs dramatically across ethnicities, we assessed robustness of PTPN22 association with SLE and its clinical subphenotypes across four ethnically diverse populations. Ten SNPs were genotyped in 8220 SLE cases and 7369 controls from in European-Americans (EA), African-Americans (AA), Asians (AS), and Hispanics (HS). We performed imputation-based association followed by conditional analysis to identify independent associations. Significantly associated SNPs were tested for association with SLE clinical sub-phenotypes, including autoantibody profiles. Multiple testing was accounted for by using false discovery rate. We successfully imputed and tested allelic association for 107 SNPs within the PTPN22 region and detected evidence of ethnic-specific associations from EA and HS. In EA, the strongest association was at rs2476601 (P = 4.761029, OR = 1.40 (95% CI = 1.25–1.56)). Independent association with rs1217414 was also observed in EA, and both SNPs are correlated with increased European ancestry. For HS imputed intronic SNP, rs3765598, predicted to be a cis-eQTL, was associated (P = 0.007, OR = 0.79 and 95% CI = 0.67–0.94). No significant associations were observed in AA or AS. Case-only analysis using lupus-related clinical criteria revealed differences between EA SLE patients positive for moderate to high titers of IgG anti-cardiolipin (aCL IgG .20) versus negative aCL IgG at rs2476601 (P = 0.012, OR = 1.65). Association was reinforced when these cases were compared to controls (P = 2.761025, OR = 2.11). Our results validate that rs2476601 is the most significantly associated SNP in individuals with European ancestry. Additionally, rs1217414 and rs3765598 may be associated with SLE. Further studies are required to confirm the involvement of rs2476601 with aCL IgG.

La efectividad de la comunicación publicitaria : un método de análisis.

Demostrar conceptualmente que es un constructo de la 'involucración' aporta una base teórica que permite generar una escala de medida, capaz de determinar, mediante una puntuación, si el producto o marca en estudio será potencialmente relevante para el consumidor. Encontrar y validar una escala capaz de disminuir el riesgo que toma de decisiones, sirviendo de ayuda en la evaluación de diferentes alternativas de comunicación publicitaria.. Para la administración de las escalas se contó con 174 varones y 76 mujeres, estudiantes universitarios entre los 18 y 30 años. Para el diseño experimental participaron 96 sujetos, todos diestros y de igual agudeza visual. 50 mujeres y 46 hombres.. El procedimiento a seguir ha sido definir los procesos implicados en el hecho publicitario desde la concepción del receptor como un procesador universal de información; investigar el concepto de involucración y su importancia en dichos procesos; generar y comparar, no sólo el instrumento basado en la involucración, sino distintas escalas de medida /tipo Fishbein/ y sus correlaciones con procedimientos más experimentales, que utilizan el tiempo de reacción /TR/ como variable dependiente, en línea con los estudios de procesamiento de información sustentados en las corrientes actuales del 'paradigma cognitivo'. El producto de consumo masivo seleccionado fue el tabaco, concretamente las marcas Winston, Camel y Marlboro. En una primera etapa del trabajo se procedió a traducir la escala propuesta por Zaichkowsky /1985/, Escala de Involucración. El procedimiento tipo Fishbein se utilizó para generar una escala relacionada con el producto y marcas en estudio. Se trata de tres diseños experimentales, uno por cada uno de las marcas en estudio, de 2X4, donde el primer factor corresponde a ser o no fumador y el segundo a la marca elegida por el sujeto.. 1. El tipo de escala escogido, si bien venía determinado por las teoría implicadas, resultó inadecuado para nuestros fines. Según nuestra experiencia las escalas tipo Fishbein pueden resultar útiles únicamente en administraciones a grupos reducidos de sujetos muy motivados y a los cuales se puede entrenar previamente en los tipos de razonamiento exigido. 2. En lo referente a la escala de involucración, creemos que las altas fiabilidades obtenidas tanto frente a marca como frente a producto, garantizan por una parte, la bondad de su traducción y, por otra, la fiabilidad de su aplicación a la población canaria. 3. Fue imposible encontrar diferencias entre los electores de las diferentes marcas, lo que, por otra parte, era de esperar en función de los resultados obtenidos en la encuesta y la explicación apuntada por los sujetos. 5. Creemos que es muy intersante la interacción encontrada entre la marca a identificar y el ser o no ser fumador.. Lo interesante de estos resultados es que apoya lo defendido por Stewart y Furse /1986/ en el sentido de que los elementos que influyen en la evocación no son los mismos que en la persuación..

Experiència d'un canvi sobre l'atenció pedagògica en un centre on atenen nens psicòtics. 'Experiencia de un cambio sobre la atención pedagógica en un centro donde atienden niños psicóticos'.

Plantear la postura que se ha de adoptar en el trabajo pedagógico con niños psicóticos. Combinar la intervención educativa con la terapeutica. Grupo de trabajo manipulativo formado por 3 niñas y 1 niño de 11 a 13 años, afectados por patologías de características psicóticas. Se describen tres centros ubicados en Barcelona (Carrilet, Alba y Gurú), especificando la línea de trabajo terapéutico, pedagógico y de tiempo Libre. Se describe el grupo pedagógico, deduciendo que las características que tienen en común es que les cuesta aceptar los cambios (de lugar físico y de interlocutores), que buscan la exclusividad del adulto y reclaman el trabajo individualizado. Se cambian las actividades centradas en la manipulación (torres, puzles, encajes) para trabajar centros de interés próximos a la vida cotidiana, más funcionales (las frutas, la calle), sin dejar por completo el trabajo manipulativo sino que se transforma para volverlo más funcional (cremalleras, lazos, botnes). Los historiales clínicos de los sujetos, la observación durante las actividades del centro. La respuesta educativa de los sujetos frente a las actividades planteadas no es del todo satisfactorio, pero se observa un progreso lento, hacia la mejora de la relación social con los educadores del centro. Concluye que los centros que atienden a niños psicóticos mezclan la interacción pedagógica con la terapéutica y se debe tener en cuenta que en los sujetos con un grado de psicosis elevado o profundo esto puede distorsionar su rendimiento.

Resumen basado en el que aporta la revista

Educación, publicidad y consumo : una mirada a la atractiva campaña de un producto poco saludable.

Debido a la creciente presencia de publicidad en todos los ámbitos de nuestra sociedad, la comunidad educativa debe esforzarse para proporcionar a los jóvenes herramientas útiles que les ayuden a ser críticos con la enorme información publicitaria que reciben y, en consecuencia, a ser buenos consumidores. En este artículo se hace un análisis exhaustivo de la campaña publicitaria gráfica de la marca de tabaco Camel, previamente se reseña la situación legal del consumo de tabaco, y la publicidad sobre el mismo en España. Se trata de una campaña con un enorme impacto sobre los adolescentes pues incide en valores como la ruptura de las normas establecidas, la aventura, la libertad o la vitalidad. Para concluir, se considera necesario restringir este tipo de publicidad, que atenta, en particular, contra la salud de los jóvenes, aumentar la publicidad formativa, crear un código ético y potenciar la formación para el consumo responsable.
