Environmental impact assessment, from Rio-92 to Rio+20 and beyond

The 1992 Rio Earth Summit was of paramount importance in the consolidation and international dissemination of environmental impact assessment, officially recognized as a tool for informed decision-making towards sustainable development (Principle 17, Rio Declaration) and for protection of biodiversity (Article 14, Convention on Biological Diversity). A significant development afterwards was the strengthening of strategic environmental assessment in the design of policies, plans and programs. Both forms of impact assessment can establish the necessary connections between one goal of the Rio+20 Conference - reaching an agreement on the transition to a green economy - and the underpinning decision making processes. Although the Rio+20 Summit has faced challenges to acknowledge its potential, impact assessment should be strengthened in support of both government and business decisions.

„This is TZ power! Kenkey can’t do this!“ : Die performative Aushandlung nationaler Kultur ; das National Festival of Arts and Culture in Ghana /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 92

Der vorliegende Artikel beschäftigt sich mit der performativen Aushandlung nationaler Kultur auf dem National Festival of Arts and Culture, das 2006 in Wa, Nordwestghana, stattfand. Die Autorin nahm an der Vorbereitung und Planung des Festivals in lokalen staatlichen Kulturinstitutionen teil, und beobachtete die Diskussionen um die Repräsentation einer (imaginierten) spezifischen Kultur des Nordens in scharfer Abgrenzung zu der des als dominant und diskriminierend empfundenen Südens. In diesem Zusammenhang werden Fragen der Authentizität und Authentifizierung, wie sie in der Planung und Rezeption diskutiert wurden, aufgegriffen und mit der Konzeption des Festivals als gleichzeitig einheitsstiftendes Vehikel für nationale Identität und als Austragungsort eines Wettbewerbs der Regionen um Anerkennung und Ressourcen in Verbindung gesetzt. Das Festival, so die Argumentation, ist eine cultural performance, die das Wesen einer „Kultur“ nicht nur abbildet, sondern auch die Möglichkeit des Wandels und der Subversion birgt. Performance meint hier also gleichzeitig die Aufführung und das Skript der Diskurse, die der Aufführung Bedeutung zuschreiben. Diesen doppelten Ansatz verfolgt der Artikel durch die Verknüpfung von Festivalbeobachtungen und Komiteesitzungsmitschriften im Rahmen der Vorbereitung.

The Effect of Respirator Wear on Blood Lactate During Maximal Exertion

The impact of a filtering half-face respirator and a half-face supplied air respirator use on blood lactate production was assessed during maximal exertion to determine if anaerobic strain increased compared to no respirator use. Twenty-eight participants performed a 30 second cycling Wingate anaerobic test (WAnT) wearing a half-face respirator. Blood lactate production was measured to evaluate if there was an increase in anaerobic strain from wearing a tight fitting half-face respirator compared to wearing no respirator. A supplied air respirator WAnT was then performed using 18 participants from the first experiment to evaluate if supplied air decreased anaerobic strain. Data from both experiments were compared to evaluate differences in the physiological effects due to respirator use during maximal exertion. A survey was administered following the second WAnT experiment to measure the participants' perception of acceptability and impact of supplied air respirator use in workplace. The blood lactate levels measured directly after the WAnT yielded lower overall mean values during the half-mask respirator trial (12.1 mmollL) and supplied air respirator trial (12.2 mmollL) than the no respirator trial (13.1 mmoI/L). However, differences in blood lactate levels were not statistically significant (p =0.597). Participants reported an average acceptability of 92.3% to wearing the supplied air respirator while performing light work. However, the average acceptability decreased as the exertion increased to moderate (78.8%) and heavy (46.6%) workloads. The supplied air respirator used provided no significant reduction in anaerobic strain within this study group compared to either the filtering half-face respirator or the no respirator condition. However, there were differences in physiological effects of respirators on each gender identified in this study. Further assessment of the anaerobic impact of respirators on each gender should be conducted.

What happens to the bone flap? Long-term outcome after reimplantation of cryoconserved bone flaps in a consecutive series of 92 patients.

BACKGROUND Reimplantation of cryoconserved autologous bone flaps is a standard procedure after decompressive craniotomies. Aseptic necrosis and resorption are the most frequent complications of this procedure. At present there is no consensus regarding the definition of the relevant extent and indication for surgical revision. The objective of this retrospective analysis was to identify the incidence of bone flap resorption and the optimal duration of follow-up. METHODS Between February 2009 and March 2012, 100 cryoconserved autologous bone flaps were reimplanted at the Department of Neurosurgery, Inselspital Bern. Three patients were not available for follow-up, and five patients died before follow-up. All patients underwent follow-up at 6 weeks and a second follow-up more than 12 months postoperatively. A clinical and CT-based score was developed for judgment of relevance and decision making for surgical revision. RESULTS Mean follow-up period was 21.6 months postoperatively (range: 12 to 47 months); 48.9 % (45/92) of patients showed no signs of bone flap resorption, 20.7 % (19/92) showed minor resorption with no need for surgical revision, and 30.4 % (28/92) showed major resorption (in 4 % of these the bone flap was unstable or collapsed). CONCLUSIONS Aseptic necrosis and resorption of reimplanted autologous bone flaps occurred more frequently in our series of patients than in most reports in the literature. Most cases were identified between 6 and 12 months postoperatively. Clinical observation or CT scans of patients with autologous bone flaps are recommended for at least 12 months. Patient-specific implants may be preferable to autologous bone flaps.
