It takes more than good intentions : institutional and attitudinal impediments to engaging young people in participatory planning

While participatory processes have become an important part of planning, young people are a particularly vulnerable group in terms of potential marginalisation and exclusion from effective participation. Including the views of young people in participatory planning is not simply a matter of bringing them into existing processes. Instead, participatory processes must find ways to integrate and accommodate their needs and ways of expressing their views. Without these adjustments young people may simply move from being kept outside the planning process to a situation where, although they are formally included, their claims are not taken seriously and they are not treated with equal respect. In this paper we reflect on the success of a community advisory committee, formed to consider water planning issues, in integrating the views of young people into their deliberations. Using Iris Marion Young’s (1995) ideas of communicative democracy we highlight the challenges and opportunities presented by this participatory approach, as articulated by both the young people involved and the adult participants. We specifically consider how the elements of greeting, rhetoric and narrative were reflected in the committee process. We argue that both planners and adult participants need to ensure that participatory processes allow for the equal engagement of all participants and place equal value on their contributions. Our research shows that this involves both an institutional and attitudinal commitment to include the views of young people. The institutional commitment requires young people to be included in processes and for their involvement to be supported. However, the attitudinal commitment it is equally important and requires that adult participants be prepared not only to accept the views of younger participants but to actively encourage and support their full participation.

DNA damage in cytologically normal urothelial cells of patients with a history of urothelial cell carcinoma

In order to determine if patients with a history of previous urothelial cell carcinoma (UCC) but with current normal urinary cytology have DNA damage in urothelial cells, the single-cell gel electrophoresis (comet) assay was conducted with cells obtained by urinary bladder washings from 44 patients (28 with a history of previous UCC). Increased DNA damage was observed in cytologically normal urothelial cells of patients with a history of UCC when compared with referents with no similar history and after correcting the data for smoking status and age (P < 0.018). Increased DNA damage also correlated with the highest tumor grade, irrespective of time or course of the disease after clinical intervention (Kendall tau correlation, 0.37, P = 0.016). Moreover, aneuploidy, as assessed by DNA content ratio (DCR; 75th/25th percentile of total DNA fluorescence of 50 comets/patient) was unaltered by smoking status, but increased with UCC grade: 1.39 +/- 0.12 (median +/- 95% confidence interval; referents); 1.43 +/- 0.11 (Grade I UCC; P = 0.264, against referents); 1.49 +/- 0.16 (Grade II UCC; P = 0.057); 1.57 +/- 0.16 (Grade III UCC; P = 0.003). Micronucleated urothelial cells (MNC) were also scored on Giemsa-stained routine cytological smears and were found not to correlate with DNA damage or DCR. MNC frequencies were higher for patients with a history of UCC and/or smoking than referents with neither history, but there was no statistical difference between groups. Taken together, these results suggest that the normal-appearing urothelium of patients resected for UCC still harbor genetically unstable cells. (C) 2002 Wiley-Liss, Inc.

Efeito da densidade de semeadura na produção do amendoim

In this work, the effects of sowing densities on peanut (Arachis hypogaea L.) crop, cv. Tatu were studied. Three experiments were carried out under field conditions on a soil classified as ''Latosol Roxo'', in the Municipality of Pontal, SP, during the wet seasons of 1987-88, 1988-89, and 1989-90. The densities studied were 7, 10, 13, 16, 19, 22, 25, and 28 seeds in one metter of row, under some row spacing of 0.60 m. The pod number per plant was the yield component responsible for the variation of pod production per plant and these decreased with the increase of sowing density. However. The low pod production per plant in high densities of sowing was compensated by the high populations of plants and these produced high yield. Thus, good pod yields were obtained, without significant losses of yield compared with the higher densities, at density of 13 seeds per meter, in 1987-88, 16 seeds per meter in 1988-89 and 10 seeds per meter in 1989-90, that resulted, respectively, in 11.36, 12.72 and 9.28 plants per meter at harvest time.

Orbital fat prolapse in a Persian cat. Case report

A two and a half-year-old female Persian cat was presented with a history of bilateral chronic ocular discharge. Epiphora bilateral mucous ocular discharge and a volume increase in bulbar conjunctiva on the dorsolateral quadrant of the right eye were noticed during routine ophthalmic examination. Ophthalmic examination and the aspiration cytology showed the presence of adipose tissue at the right eye dorsolateral quadrant indicating orbital fat prolapse.

Locomotor velocity and striatal adaptive gene expression changes of the direct and indirect pathways in Parkinsonian rats

BACKGROUND In Parkinson's disease (PD), bradykinesia, or slowness of movement, only appears after a large striatal dopamine depletion. Compensatory mechanisms probably play a role in this delayed appearance of symptoms. OBJECTIVE Our hypothesis is that the striatal direct and indirect pathways participate in these compensatory mechanisms. METHODS We used the unilateral 6-hydroxydopamine (6-OHDA) rat model of PD and control animals. Four weeks after the lesion, the spontaneous locomotor activity of the rats was measured and then the animals were killed and their brain extracted. We quantified the mRNA expression of markers of the striatal direct and indirect pathways as well as the nigral expression of dopamine transporter (DAT) and tyrosine hydroxylase (TH) mRNA. We also carried out an immunohistochemistry for the striatal TH protein expression. RESULTS As expected, the unilateral 6-OHDA rats presented a tendency to an ipsilateral head turning and a low locomotor velocity. In 6-OHDA rats only, we observed a significant and positive correlation between locomotor velocity and both D1-class dopamine receptor (D1R) (direct pathway) and enkephalin (ENK) (indirect pathway) mRNA in the lesioned striatum, as well as between D1R and ENK mRNA. CONCLUSIONS Our results demonstrate a strong relationship between both direct and indirect pathways and spontaneous locomotor activity in the parkinsonian rat model. We suggest a synergy between both pathways which could play a role in compensatory mechanisms and may contribute to the delayed appearance of bradykinesia in PD.

Facilitating Inclusion: Austrian Wisdom Councils as Democratic Innovation between Consensus and Diversity

Democratic innovations face the challenge of realizing deliberative democratic ideals in the context of structural inequality. Consensus decision making and expertise have been said to have exclusive effects on marginalized groups like women and ethnic and sexual minorities, which obstructs diversity. Wisdom Councils as practiced in Austria attempt to counter inequalities by including marginalized groups through the moderation technique dynamic facilitation. Exploratory participatory observations and interviews with a moderator and the participants of two Wisdom Councils in Austria provide a deeper understanding of the inclusive processes at work in Wisdom Councils facilitating a productive combination of consensus and diversity.

Percentiles de la prueba de carrera de ida y vuelta 4x10 m en escolares de 9 a 17 años de Bogotá, Colombia: Estudio FUPRECOL

Objetivo: Este estudio describe los percentiles de la prueba de carrera de ida y vuelta 4 x 10 m en escolares de 9 a 17 años, de Bogotá, Colombia, pertenecientes al estudio Asociación de la fuerza prensil con manifestaciones tempranas de riesgo cardiovascular en niños colombianos. “FUPRECOL” Métodos: Estudio descriptivo transversal, en 2502 varones (42.7%) y 3349 mujeres (57,2%), de edades entre 9 y 17 años, pertenecientes a 24 instituciones educativas del sector oficial, en Bogotá, Colombia. La velocidad/agilidad se evaluó con la prueba de carrera de ida y vuelta 4 x 10 m (componente motor de la batería Fuprecol). Se calcularon los percentiles (P3, P10, P25, P50, P75, P90 y P97) y curvas centiles por el método LMS, según el sexo y la edad; y se realizó una comparación entre los valores de la velocidad-agilidad observados con estudios internacionales. Resultados: La edad promedio de los participantes fue 12,7 (DE 2,4) años. Al comparar por sexos, los varones presentan un mejor rendimiento en la prueba de carrera 4 x 10 m que las mujeres. En varones, el P50 osciló entre 11,9 segundos y 13,1 segundos, mientras que en mujeres el P50 osciló entre 14,3 segundos y 15,0 segundos. Al comparar los resultados de este estudio por grupos de edades y sexos, con trabajos internacionales, el P50 fue mayor al reportado en los trabajos de España, Portugal y el estudio HELENA realizado en 9 países europeos. Esta misma tendencia fue observada al comparar la media y la desviación estándar con escolares de Argentina, Francia y el mismo estudio HELENA. Conclusiones: Se registran percentiles de la prueba de carrera de ida y vuelta 4 x 10 m en función de las edades y el sexo. Estos valores pueden ser utilizados tanto para evaluar los niveles de aptitud de los estudiantes como para detectar a estudiantes cuyos niveles de condición física están por debajo de un mínimo saludable.
