- The Socioeconomic Impact of Truffle Cultivation in Rural Spain. Commercial black truffle (Tuber melanosporum) plantations have been promoted in Europe with the intention of benefiting rural economies while conserving biodiversity through the expansion of oak woodlands. In this context, a socioeconomic study was conducted around the town of Sarrion in eastern Spain, where government subsidies have supported oak reforestation and truffle cultivation in unproductive hilly areas since 1987. Currently there are about 4,500 ha of truffle orchards in the surrounding county and 530 members in the local truffle association, which has provided a key forum for truffle cultivators to share technical, financial and administrative experiences. Structured interviews were carried out in 2002 with a number of orchard owners, as well as representatives of financial and governmental institutions. Truffles, which are harvested using trained dogs, typically fetch local cultivators average prices of 220-670 EUR/kg, although retail prices of high-quality specimens may reach twice this amount. In addition to the direct economic impact, an increase in local land prices was also documented, as well as a tendency for continued expansion of truffle orchards, and thus oak reforestation. In conclusion, the promotion of truffle cultivation through autonomous community and provincial government subsidies, in conjunction with support by local banks, a dedicated local truffle association, and growing interest on behalf of local farmers, seems to have achieved the mutual goals of biodiversity conservation and improving the rural economy in this region of Spain.

- Hur når vi målen som rör informationskompetens i vår undervisning? Frågan ställdes av en lärare och en bibliotekarie vid Odontologiska fakulteten på Malmö högskola. Den ledde till ett samarbete där bibliotekariens undervisning integrerades helt i fallstudierna på tandteknikerutbildningen. Artikeln beskriver upplägg och genomförande av en modell där informationskompetens och problembaserat lärande kombineras (här kallat IK&PBL-modellen). Bibliotekariens pedagogiska förhållningssätt, i form av problembaserat lärande, är karaktäristisk för den övriga utbildningen på tandvårdshögskolan. Tentamensresultat och kursutvärderingar visar att IK&PBL-modellen bidrar till att utveckla studenternas förmåga att söka information och granska källkritiskt samt ger upphov till diskussioner omkring begreppet vetenskaplighet. Bibliotekarien får en inblick i studenternas utbildning, ökad ämneskunskap och förståelse för inlärningsprocessen medan läraren får insyn i studenternas problem med informationssökning och källkritik.

- A complex system of waves propagating inside a water column due to the impact of plane shock wave is investigated both experimentally and numerically. Flow features, such as, focusing of expansion waves generating large negative pressure, nucleation of cavitation bubbles, and a re-circulation zone are observed and discussed qualitatively and quantitatively. Experiments are conducted on a 22 mm diametrical water column hit by shock waves with Mach numbers 1.75 and 2.4 in a newly constructed exploding wire facility. A new technique to create a properly shaped, repeatable, large diameter water column with straight walls is presented. Qualitative features of the flow are captured using the shadowgraph technique. With the aid of numerical simulations the wave motions inside the column are analyzed; the spatial location of the expansion wave focusing point and the corresponding negative peak pressures is estimated.

Strategies and Success in Litigation and Negotiation in the WTO

- This article analyzes linkages between litigation in the World Trade Organization (WTO) Dispute Settlement Body (DSB) and negotiation in multilateral trade rounds and develops a typology of links that can occur between the two processes. These include creating conditions where bargaining is informed by law, influencing the agenda-setting and creating momentum for negotiation on key issues, and affecting the status quo from which negotiations proceed by influencing nterpretation of trade rules in the DSB. The purpose is to test whether poor and inexperienced states that are disadvantaged in negotiations can improve their bargaining power in negotiation rounds by pursuing legal proceedings, to see whether links can be exploited for strategy-making to promote the interests of these states, and to discuss how the WTO as an international organization benefits from their empowerment. The strategies suggested in this article could improve the commitment and active participation of relatively non-influential member states. This could be conducive to perceptions of the WTO as a legitimate organization and to a more constructive climate for effective negotiations.

- 1. Opportunistically collected species observations contributed by volunteer reporters are increasingly available for species and regions for which systematically collected data are not available. However, it is unclear if they are suitable to produce reliable habitat suitability models (HSMs), and hence if the species-habitat relationships found and habitat suitability maps produced can be used with confidence to advice conservation management and address basic and applied research questions.2. We evaluated HSMs with opportunistically collected observations against HSMs with systematically collected observations. We enhanced the opportunistically collected presence-only data by adding inferred species absences. To obtain inferred absences, we asked individual reporters about their identification skills and if they reported certain species consistently and combined this information with their observations. We evaluated several HSM methods using a forest bird species, Siberian jay (Perisoreus infaustus), in Sweden: logistic regression with inferred absences, two versions of MaxEnt, a model combining presence-absence with presence-only observations and a Bayesian site-occupancy-detection model.3. All HSM methods produced nationwide habitat suitability maps of Siberian jay that agreed well with systematically collected observations (AUC: 086-0.88) and were very similar to a habitat suitability map produced from the HSM with systematically collected observations (Spearman rho: 0.94-0.98). At finer geographical scales there were differences among methods.4. At finer scale, the resulting habitat suitability maps from logistic regression with inferred absences agreed better with results from systematically collected observations than other methods. The species-habitat relationships found with logistic regression also agreed well with those found from systematically collected data and with prior expectations based on the species ecology.5. Synthesis and application. For many regions and species, systematically collected data are not available. By using inferred absences from high-quality, opportunistically collected contributions of few very active reporters in logistic regression we obtained HSMs that produced results similar to those from a systematic survey. Adding high-quality inferred absences to opportunistically collected data is likely possible for many less common species across various organism groups. Well-performing HSMs are important to facilitate applications such as spatial conservation planning and prioritization, monitoring of invasive species, understanding species habitat requirements or climate change studies.
