Successful, long-term implementation of Integrated Pest Management (IPM) requires the integration of key technical and management activities and the participation of a wide range of stakeholders including farmers, researchers, extension officers, crop consultants, government agencies, and industry. A key issue that needs urgent attention is how to achieve the high quality interaction between these different groups which is necessary for sustained IPM. Problem specification and planning workshops (PSPWs) provide one means of facilitating an integrated strategy for tackling complex pest management issues. Since 1992, the Cooperative Research Centre for Tropical Pest Management has facilitated over 20 PSPWs, focusing on different farming systems in Australia. This paper describes the philosophy, the process involved, and the impact that these PSPWs have had. It examines three specific cases to describe the relationship between plans and results and ways of improving impact. The results reinforce the major role that social scientists can play in providing mechanisms for collaborating with technical researchers and other partners to facilitate effective, participatory ventures in IPM.

A vállalati fenntarthatósági teljesítményértékelésre vonatkozóan számtalan megközelítés és módszer létezik. Ez a cikk a lábnyomtípusú fenntarthatósági mutatók vállalati teljesítményértékelésben betöltött szerepéről kíván összegző áttekintést nyújtani. A lábnyomtípusú mutatók alkalmazásával kapcsolatban számos elméleti modell és gyakorlati tapasztalat áll rendelkezésre, ezek ugyanakkor kevéssé foglalkoznak a lábnyom-megközelítések szervezeti szintű alkalmazásával, illetve annak rendszerszintű áttekintésével. E cikkben ezért a szerzők felvázolnak egy keretrendszert a vállalati fenntarthatósági lábnyom-indikátorok értékelésére, amelyen keresztül megvizsgálják a leggyakoribb lábnyom-megközelítések vállalati fenntarthatósági teljesítményértékelésben betöltött lehetséges szerepét. A felvázolt modell kiterjed i) a teljesítményértékelési folyamat tervezésének, ii) az információgyűjtés folyamatának és iii) a teljesítményértékelési rendszer felülvizsgálatának és fejlesztésének belső és külső szempontjaira. Az áttekintés során összesen öt különböző vállalati lábnyomtípust azonosítottak, melyek szervezeti szinten is alkalmazhatóak (karbonlábnyom, ökológiai lábnyom, vízlábnyom, környezeti lábnyom és nitrogénlábnyom). Ezek tartalmukat és módszertani kidolgozottságukat tekintve igen eltérőek. Közös jellemzőjük, hogy a vállalatok és más szervezetek számára lehetőséget adnak a szervezeti szintű fenntarthatósági teljesítményük nyomon követésére, kezelésére és kommunikálására. Mivel a lábnyomok a közvetlen hatások mellett a közvetett hatásokról is képesek információt nyújtani, kulcsszerepet tölthetnek be a szervezeti fenntarthatóság mérésében.

A globalizálódó világgazdaságban a vezető bortermelő országok egyre jelentősebb borkereskedelmet bonyolítanak le egymás között. Míg Európában a fogyasztók egyre kevesebb bort vásárolnak, addig Amerikában és Ázsiában a bor iránti kereslet folyamatosan bővül: a borkereskedelem földrajzi átrendeződése zajlik. A kulturális hasonlóság és a földrajzi távolság kereskedelemre gyakorolt hatását gyakran a kereskedelemelméletek gravitációs modelljével elemzik. E tanulmány azt vizsgálja, hogy a fő borexportáló országok közötti földrajzi távolság, kulturális hasonlóság és szabadkereskedelem milyen hatással van a nemzetközi borkereskedelemre, annak költségeire. A regressziós becslés eredményei alátámasztják, hogy a borkereskedelem költségei alacsonyabbak, ha a kereskedelmi partnerek kulturálisan hasonlók, földrajzilag közel helyezkednek el egymáshoz, vagy van tengeri kikötőjük, tagjai a WTO-nak, illetve ha kötöttek egymással regionális kereskedelmi megállapodást. Ezenkívül megállapítható, hogy az angolszász, a latin-amerikai és az európai kulturális klaszterek elsősorban egymással kereskednek. A kutatás számos kulturális változó alkalmazásával és több ökonometriai modell, illetve becslési eljárás nagymintás tesztelésével gazdagítja a szakirodalmat. ____ In a globalizing world, major wine-producing countries export considerable quantities to the global wine market and turn over a notable trade, but in what happens European wine regions differ markedly from the New World. Here major wine producers suffered a remarkable fall in domestic wine consumption in recent decades, while New World wine producers increased their production potential and generated new foreign demand. The changes have been joined by geographical relocation of wine consumption and exports. The gravity equation can be derived from demand-side or supply-side theory-consistent estimation methods that suggest relationships between the size of the economies, geographical distances, cultural similarities, and size of their trade. The paper analyses the effects of cultural and geographical proximity, free trade, and linguistic similarity on bilateral trade in the main wine-producing countries, using a cross-section gravity model for 2012. The results suggest that larger countries export more wine, while transport costs rise in line with geographical distance and are higher for landlocked trading partners. Wine export costs are lower if trading partners are culturally similar, share a dominant religion, or are both WTO members with regional trade agreements. Anglo-Saxon, Germanic, Latin American and Latin European countries mainly trade wines within their groups. The paper looks to extend the number of trading partners, investigate the effect of language clusters, and confirm that the results are robust by different econometric methodologies.

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

The concentration of C37-C39 long-chain alkenones and alkenes were determined in surface water and surface sediment samples from the subpolar waters of the Southern Ocean. Distributions of these compounds were similar in both sample sets indicating little differential degradation between or within compound classes. The relative amounts of the tri- to tetra-unsaturated C37 alkenones increased with increasing temperature for temperatures below 6°C similar to the di- and tri-unsaturated C37 alkenones. The C37 di-, tri-, and tetra-unsaturated methyl alkenones are used in paleotemperature calculations via the U37K and the U37K ratios. In these datasets, the relative abundances of the C37:2 and the C37.3 alkenones as a proportion of the total C37 alkenones were opposite and strongly related to temperature (the latter with more scatter), but the abundance of the C37:4 alkenone showed no relationship with temperature. The original definition of U37K includes the abundance of 37:4 in both the numerator and denominator, and thus it is perhaps not surprising that there is considerable scatter in the values obtained for U37K at low temperatures. Of the two, we suggest that U37K' is the better parameter for use in paleotemperature estimations, even in cold locations. U37K' values in the sediments fall on virtually the same regression line obtained for the water column samples of Sikes and Volkman (1993, doi:10.1016/0016-7037(93)90120-L), indicating that their calibration is suitable for use in Southern Ocean sediments. The comparison of water column data with sedimentary temperature estimates suggests that the alkenone distributions are dominated by contributions from the summer when the biomass of Emiliania huxleyi and presumably flux to the sediment, is expected to be high.

Planktic foraminifers Neogloboquadrina pachyderma (sin.) from 87 eastern and central Arctic Ocean surface sediment samples were analyzed for stable oxygen and carbon isotope composition. Additional results from 52 stations were taken from the literature. The lateral distribution of delta18O (18O/16O) values in the Arctic Ocean reveals a pattern of roughly parallel, W-E stretching zones in the Eurasian Basin, each ~0.5 per mil wide on the delta18O scale. The low horizontal and vertical temperature variability in the Arctic halocline waters (0-100 m) suggests only little influence of temperature on the oxygen isotope distribution of N. pachyderma (sin.). The zone of maximum delta18O values of up to 3.8 per mil is situated in the southern Nansen Basin and relates to the tongue of saline (> 33%.) Atlantic waters entering the Arctic Ocean through the Fram Strait. delta18O values decrease both to the Barents Shelf and to the North Pole, in accordance with the decreasing salinities of the halocline waters. In the Nansen Basin, a strong N-S delta18O gradient is in contrast with a relatively low salinity change and suggests contributions from different freshwater sources, i.e. salinity reduction from sea ice meltwater in the south and from light isotope waters (meteoric precipitation and river-runoff) in the northern part of the basin. North of the Gakkel Ridge, delta18O and salinity gradients are in good accordance and suggest less influence of sea ice melting processes. The delta13C (13C/12C) values of N. pachyderma (sin.) from Arctic Ocean surface sediment samples are generally high (0.75-0.95 per mil). Lower values in the southern Eurasian Basin appear to be related to the intrusion of Atlantic waters. The high delta13C values are evidence for well ventilated surface waters. Because the perennial Arctic sea ice cover largely prevents atmosphere-ocean gas exchange, ventilation on the seasonally open shelves must be of major importance. Lack of delta13C gradients along the main routes of the ice drift from the Siberian shelves to the Fram Strait suggests that primary production (i.e. CO2 consumption) does probably not change the CO2 budget of the Arctic Ocean significantly.

The successful use of helminths as therapeutic agents to resolve inflammatory disease was first recorded 40 years ago. Subsequent work in animal models and in humans has demonstrated that the organisms might effectively treat a wide range of inflammatory diseases, including allergies, autoimmune disorders and inflammation-associated neuropsychiatric disorders. However, available information regarding the therapeutic uses and effects of helminths in humans is limited. This study probes the practices and experiences of individuals 'self-treating' with helminths through the eyes of their physicians. Five physicians monitoring more than 700 self-treating patients were interviewed. The results strongly support previous indications that helminth therapy can effectively treat a wide range of allergies, autoimmune conditions and neuropsychiatric disorders, such as major depression and anxiety disorders. Approximately 57% of the self-treating patients observed by physicians in the study had autism. Physicians reported that the majority of patients with autism and inflammation-associated co-morbidities responded favourably to therapy with either of the two most popular organisms currently used by self-treaters, Hymenolepis diminuta and Trichuris suis. However, approximately 1% of paediatric patients experienced severe gastrointestinal pains with the use of H. diminuta, although the symptoms were resolved with an anti-helminthic drug. Further, exposure to helminths apparently did not affect the impaired comprehension of social situations that is the hallmark of autism. These observations point toward potential starting points for clinical trials, and provide further support for the importance of such trials and for concerted efforts aimed at probing the potential of helminths, and perhaps other biologicals, for therapeutic use.

Copyright © 2014 International Anesthesia Research Society.BACKGROUND: Goal-directed fluid therapy (GDFT) is associated with improved outcomes after surgery. The esophageal Doppler monitor (EDM) is widely used, but has several limitations. The NICOM, a completely noninvasive cardiac output monitor (Cheetah Medical), may be appropriate for guiding GDFT. No prospective studies have compared the NICOM and the EDM. We hypothesized that the NICOM is not significantly different from the EDM for monitoring during GDFT. METHODS: One hundred adult patients undergoing elective colorectal surgery participated in this study. Patients in phase I (n = 50) had intraoperative GDFT guided by the EDM while the NICOM was connected, and patients in phase II (n = 50) had intraoperative GDFT guided by the NICOM while the EDM was connected. Each patient's stroke volume was optimized using 250- mL colloid boluses. Agreement between the monitors was assessed, and patient outcomes (postoperative pain, nausea, and return of bowel function), complications (renal, pulmonary, infectious, and wound complications), and length of hospital stay (LOS) were compared. RESULTS: Using a 10% increase in stroke volume after fluid challenge, agreement between monitors was 60% at 5 minutes, 61% at 10 minutes, and 66% at 15 minutes, with no significant systematic disagreement (McNemar P > 0.05) at any time point. The EDM had significantly more missing data than the NICOM. No clinically significant differences were found in total LOS or other outcomes. The mean LOS was 6.56 ± 4.32 days in phase I and 6.07 ± 2.85 days in phase II, and 95% confidence limits for the difference were -0.96 to +1.95 days (P = 0.5016). CONCLUSIONS: The NICOM performs similarly to the EDM in guiding GDFT, with no clinically significant differences in outcomes, and offers increased ease of use as well as fewer missing data points. The NICOM may be a viable alternative monitor to guide GDFT.
