  ABSTRACT: Graduates of university programs addressing sustainable resource management are likely to shape strategies for natural resource use in the future. Their academic training needs to foster student knowledge of the multiple dimensions of natural resource management. This paper investigates university student understanding of such challenges. We differentiated situational, conceptual, and procedural types of knowledge, and three domains of knowledge (ecological, socio-economic and institutional knowledge), and sampled beginners (third semester) and seniors (seventh semester) of seven natural resource related programs at the leading Indonesian institution of higher education in the field of natural resource management (IPB Bogor; n = 882). The questionnaire consisted of multiple choice and rating scale items covering ‗locally‘ relevant open-access resource use issues. With a confirmatory tau-equivalent LISREL model, construct validity was assessed. The ability to extract relevant information from problem descriptions provided (situational knowledge) did not differ between third and seventh semester students. While it was high for ecological and socio-economic items, it was markedly lower for institutional knowledge. Knowledge of relevant scientific concepts (conceptual knowledge) increased in the ecological and socio-economic domains but the effect was small. Conceptual knowledge in the socio-economical and institutional domains tended to be lower than ecological knowledge. Although there was certain improvement, student judgments on the efficacy of resource management options (procedural knowledge) differed strongly from expert judgments for beginners as well as for senior students. We conclude that many of the university students in the sampled programs displayed substantial gaps in their capacity to solve complex, real-world natural resource management problems. Specifically, the socio-economic and institutional knowledge domains—and their integration with ecological knowledge—may require attention by educational planners.

  Article: The value structure in socioeconomically less developed European countries still remains an ellipse.

  ABSTRACT: Based on the 21-item Human Values Scale of the European Social Survey (ESS, 2002–2006) Bilsky, Janik, and Schwartz (2011) concluded that the quasi-circular model of Schwartz’s value theory “fits somewhat less well in less developed societies” (p. 16). This article focuses on their mitigating quantifier “somewhat” and proposes an impartial measure to evaluate Schwartz’s universality claim. European Social Survey data of four rounds 2002–2008 (33 countries, 98 samples) were analysed. Applying restricted confirmatory factor analysis (CFA), we partitioned the 21 items’ variance into an acquiescence part and the two diagonal axes of growth-protection and social-personal focused values. The variance in the growth–protection axis varied between 22.0% (Austria, in 2002) and 2.0% (samples from Romania, Turkey, Ukraine, Hungary, and Slovakia remain below 5%). Within rounds across countries (respective df = 94), the growth–protection axis’ variance strongly correlates (r = .76) with an index of socioeconomic development, aggregated from five indicators adopted from the World Bank. It also strongly correlates (r = .81) with a sample’s mean member’s location on the growth vs. protection value dimension. We interpret these results as a strong effect and conclude that in socioeconomically less developed countries the value structure remains elliptical or even one-dimensional. The discussion relates the results to Klages’ value synthesis theory.

  ABSTRACT: The i-gel™, LMA-Supreme (LMA-S) and Laryngeal Tube Suction-D (LTS-D) are single-use supraglottic airway devices with an inbuilt drainage channel. We compared them with regard to their position in situ as well as to clinical performance data during elective surgery. Prospective, randomized, comparative study of three groups of 40 elective surgical patients each. Speed of insertion and success rates, leak pressures (LP) at different cuff pressures, dynamic airway compliance, and signs of postoperative airway morbidity were recorded. Fibreoptic evaluation was used to determine the devices' position in situ. Leak pressures were similar (i-gel™ 25.9, LMA-S 27.1, LTS-D 24.0 cmH2O; the latter two at 60 cmH2O cuff pressure) as were insertion times (i-gel™ 10, LMA-S 11, LTS-D 14 sec). LP of the LMA-S was higher than that of the LTS-D at lower cuff pressures (p <0.05). Insertion success rates differed significantly: i-gel™ 95%, LMA-S 95%, LTS-D 70% (p <0.05). The fibreoptically assessed position was more frequently suboptimal with the LTS-D but this was not associated with impaired ventilation. Dynamic airway compliance was highest with the i-gel™ and lowest with the LTS-D (p <0.05). Airway morbidity was more pronounced with the LTS-D (p <0.01). All devices were suitable for ventilating the patients' lungs during elective surgery. German Clinical Trial Register DRKS00000760.
