Participação política no Brasil: ação coletiva e interfaces socioestatais

Essa coletânea reúne alguns trabalhos apresentados e discutidos no “Encontro internacional participação, democracia e políticas públicas: aproximando agendas e agentes”, realizado na Faculdade de Ciências e Letras da Unesp de Araraquara em abril de 2013. O encontro foi organizado pelo Grupo de Pesquisa Participação, Democracia e Políticas Públicas, formado por docentes e pesquisadores ligados ao Departamento de Antropologia, Política e Filosofia e também ao Departamento de Administração Pública desta faculdade. A proposta do encontro partiu do diagnóstico de ambos os departamentos da necessidade de se ampliar os debates que relacionem as temáticas da participação, das políticas públicas e da democracia no Brasil e na América Latina, no atual contexto de insuficiência das instituições políticas calcadas no âmbito da democracia liberal e de uma notória “crise da representação”. O livro foi dividido em três partes, “Ação coletiva e institucionalização: interfaces socioestatais”, que trata dos processos de institucionalização dos movimentos sociais; “Instituições participativas da teoria à implementação: dilemas e desafios”, sobre estratégias de governança; e “Participação como política e a política da participação: difusão, impactos, poder”, sobre políticas públicas e o trabalho das ONGs nas ações governamentais.

Thermoperiod affects the diurnal cycle of nitrate reductase expression and activity in pineapple plants by modulating the endogenous levels of cytokinins

Nitrate reductase (NR, EC 1.6.6.1) activity in higher plants is regulated by a variety of environmental factors and oscillates with a characteristic diurnal rhythm. In this study, we have demonstrated that the diurnal cycle of NR expression and activity in pineapple (Ananas comosus, cv. Smooth Cayenne) can be strongly modified by changes in the day/night temperature regime. Plants grown under constant temperature (28 degrees C light/dark) showed a marked increase in the shoot NR activity (NRA) during the first half of the light period, whereas under thermoperiodic conditions (28 degrees C light/15 degrees C dark) significant elevations in the NRA were detected only in the root tissues at night. Under both conditions, increases in NR transcript levels occurred synchronically about 4 h prior to the corresponding elevation of the NRA. Diurnal analysis of endogenous cytokinins indicated that transitory increases in the levels of zeatin, zeatin riboside and isopentenyladenine riboside coincided with the accumulation of NR transcripts and preceded the rise of NRA in the shoot during the day and in the root at night, suggesting these hormones as mediators of the temperature-induced modifications of the NR cycle. Moreover, these cytokinins also induced NRA in pineapple when applied exogenously. Altogether, these results provide evidence that thermoperiodism can modify the diurnal cycle of NR expression and activity in pineapple both temporally and spatially, possibly by modulating the day/night changes in the cytokinin levels. A potential relationship between the day/night NR cycle and the photosynthetic pathway performed by the pineapple plants (C(3) or CAM) is also discussed.

"Även om jag bor här i 100 år så blir det inte samma" : En kvalitativ studie av fem ensamkommande ungdomar och deras personliga identitetsutveckling i mottagarlandet.

SAMMANFATTNING: Människor tvingas fly ifrån sina hemländer på grund av våld för att söka säkerhet någon annanstans. Att människor lämnar ett land eller tvingas fly har skett under alla tider. Människor flyr från förföljelse, fattigdom, svält eller krig. Uppskattningsvis finns 19,2 miljoner människor på flykt runt om i världen och nära hälften av dessa är barn. Av de barn som befinner sig på flykt är de ensamkommande ungdomarna en viktig grupp att urskilja. Då de ensamkommande asylsökande ungdomarna är i behov av särskilt skydd. Under 2003 var de flesta ensamkommande ungdomar i Sverige från Somalia, Irak, Serbien och Montenegro. Vårt syfte är att få ökad förståelse för ensamkommande ungdomars upplevelser av hur deras identitet formats i hemlandet och senare i mottagarlandet i samspel med människor i sin omgivning. Samt vilken betydelse asylprocessen och tidigare trauman har haft för ungdomarnas personliga identitetsutveckling. De faktorer som berörts som viktiga för ungdomens personliga identitetsutveckling är förluster, boende, ovisshet, familjeåterförening och nätverk samt språket.Vi har valt att göra en explorativ studie som innefattar kvalitativa halvstrukturerade intervjuer med fem ensamkommande ungdomar. Resultatet i form av empiri och analys har utförts utifrån tidigare forskning och från Cullbergs kristeori samt relevanta begrepp som etnicitet och identitet utifrån symbolisk interaktionism. Studien har visat att samtliga ungdomar upplevt att den ovisshet de levt i under asylprocessen samt tidigare trauman har påverkat dem mycket både psykiskt och fysiskt. De ungdomar vi har intervjuat upplever alla att de idag har en ny personlighet efter att ha fått uppehållstillstånd. Den nya identiteten har enligt ungdomarna påverkats bland annat av föräldrarnas uppfostran och de nya människor de möter i mottagarlandet samt av de nya miljöerna ungdomarna befinner sig i.

NO2-induced nitrate reductase activity in needles of Norway spruce (Picea abies) under laboratory and field conditions

The induction of activity of the enzyme nitrate reductase (NR, EC 1.6.6.1, 1.6.6.2) in needles of Norway spruce (Picea abies[L.] Karst.) by nitrogen dioxide (NO2) was studied under laboratory and field conditions. In fumigation chambers an increase in nitrate reductase activity (NRA) was detected 4 h after the start of the NO2 treatment. During the first 2 days with 100 µg NO2 m−3, NRA reached a constant level and did not change during the following 4 days. At the same level of NO2, NRA was lower in needles from trees grown on NPK-fertilized soil than on non-fertilized soil. After the transfer of spruce trees from fertilized soil to NPK-rich nutrient solution, NRA was transiently increased. This effect was assigned to root injuries causing nitrate transport to the shoot and subsequent induction of NRA. Neither trees on fertilized soil nor trees transferred to NPK-poor nutrient solution had increased NRA unless NO2 was provided. The NO2 gradient in the vicinity of a highway was used to test the long-term effect of elevated levels of NO2 on needle NRA of potted and field-grown spruce trees. Compared with less polluted sites, permanently increased NRAs were detected when NO2 concentrations were above 20 µg m−3. Controls of field measurements some 10 years after the introduction of catalytic converters in cars showed no significant change neither in NO2 levels nor in the decreasing NRA of spruce needles with the distance from the highway.

Temporal distribution of the ganglion cell volleys in the normal rat optic nerve

We describe experiments on behaving rats with electrodes implanted on the cornea, in the optic chiasm, and on the visual cortex; in addition, two red light-emitting diodes (LED) are permanently attached to the skull over the left eye. Recordings timelocked to the LED flashes reveal both the local events at each electrode site and the orderly transfer of visual information from retina to cortex. The major finding is that every stimulus, regardless of its luminance, duration, or the state of retinal light adaptation, elicits an optic nerve volley with a latency of about 10 ms and a duration of about 300 ms. This phenomenon has not been reported previously, so far as we are aware. We conclude that the retina, which originates from the forebrain of the developing embryo, behaves like a typical brain structure: it translates, within a few hundred milliseconds, the chemical information in each pattern of bleached photoreceptors into a corresponding pattern of ganglion cell neuronal information that leaves via the optic nerve. The attributes of each rat ganglion cell appear to include whether the retinal neuropile calls on it to leave after a stimulus and, if so when, within a 300-ms poststimulus epoch. The resulting retinal analysis of the scene, on arrival at the cortical level, is presumed to participate importantly in the creation of visual perceptual experiences.

Sleep modifies retinal ganglion cell responses in the normal rat

Recordings were obtained from the visual system of rats as they cycled normally between waking (W), slow-wave sleep (SWS), and rapid eye movement (REM) sleep. Responses to flashes delivered by a light-emitting diode attached permanently to the skull were recorded through electrodes implanted on the cornea, in the chiasm, and on the cortex. The chiasm response reveals the temporal order in which the activated ganglion cell population exits the eyeball; as reported, this triphasic event is invariably short in latency (5–10 ms) and around 300 ms in duration, called the histogram. Here we describe the differences in the histograms recorded during W, SWS, and REM. SWS histograms are always larger than W histograms, and an REM histogram can resemble either. In other words, the optic nerve response to a given stimulus is labile; its configuration depends on whether the rat is asleep or awake. We link this physiological information with the anatomical fact that the brain dorsal raphe region, which is known to have a sleep regulatory role, sends fibers to the rat retina and receives fibers from it. At the cortical electrode, the visual cortical response amplitudes also vary, being largest during SWS. This well known phenomenon often is explained by changes taking place at the thalamic level. However, in the rat, the labile cortical response covaries with the labile optic nerve response, which suggests the cortical response enhancement during SWS is determined more by what happens in the retina than by what happens in the thalamus.

In-house lawyers of NRAs may not represent their clients before the European Court of Justice: A case note on UKE (2011). Research Papers in Law, 3/2011

From the Introduction. It is not frequent for a National Regulation Authority (NRA) to bring an action against the Commission decision and, cynically speaking, case Prezes Urzędu Komunikacji Elektronicznej2 v Commission3 shows that the avoidance of a sweeping retaliation may be one of the reasons for it. The General Court followed the Commission‟s argument that, notwithstanding the peculiarities of the employment conditions of the Polish Regulator‟s legal counsel giving it virtually full independence, as well as the fact that the Polish law itself does not differentiate between in-house counsel and third party attorneys, the claim should be rejected on the grounds of inadmissibility. The GC based its judgment on Art 19 of the Statute of the Court of Justice4, which requires that, with the exception of the Member States' Governments and the EU Institutions, parties to the dispute must be represented by a lawyer. In so doing, the Court explicitly referred to the infamous Akzo Nobel Chemicals and Akcros Chemicals v Commission5 and EREF v Commission6. Most importantly, the Court stated that the lawyers representing Prezes Urzędu Komunikacji Elektronicznej (UKE) are bound to enjoy a degree of independence inferior to that of lawyers who are not linked to their clients by an employment contract7.
