Knowledge networks and Australian Football League coach development: People of influence

Australian Football League (AFL) generally recognised as the ‘national game’ in Australia has a well established program of coach development. However, research examining AFL coaches’ work and how they learn to perform that work has hitherto not been conducted. The effective preparation of coaches is of prime concern to the AFL and should be informed by an examination of how coaches within the code come to know how to do their coaching work. Therefore, the purpose of this AFL-funded research was to inform coach development programs for current and aspiring AFL coaches.

Evaluation of anti-inflammatory potential of Chloranthus erectus (Buch.-Ham.) Verd. leaf extract in rats

Aim of the study: Chloranthus erectus (Buch.-Ham.) Verdcourt (Chloranthaceae) is a shrub native to tropical and temperate zone of Eastern Himalaya of India and South-East Asia and have traditionally been used as a folklore medicine to treat localised swelling, joint pain, skin inflammation, fever and bodyache. In this study, an attempthas been made to demonstrate the anti-inflammatory activity of methanol extract obtained from Chloranthus erectus leaves (MECEL) in acute, sub-acute and chronic mouse models. Materials and methods: Inflammation in the hind paw of Wistar albino rat was induced by carrageenan, histamine and serotonin, and tissue granuloma pouch was induced by cotton pellet method. Antiinflammatory drug-phenylbutazone was used as standard drug for comparison. Results: In acute carrageenan-induced rat hind paw edema, oral administration of MECEL at 200 mg/kg produced significant inhibition of edema by 38.34 % (p<0.01) while the histamine- and serotonin-induced sub-acute model, the inhibition of paw edema reached 52.54 % (p < 0.001) and 25.5 % (p < 0.01), respectively. in a 7-day study, MECEL at 20 and 50 mg/kg produced significant suppression of cotton pellet-induced tissue granuloma formation in rats. Conclusions: This preliminary study revealed that the methanol extract of Chloranthus erectus exhibited significant anti-inflammatory activity in the tested models, and may provide the scientific rationale for its popular folk medicine as anti-inflammatory agent.

On the behaviour of some physical parameterization methods in high-resolution numerical weather prediction models

Modern-day weather forecasting is highly dependent on Numerical Weather Prediction (NWP) models as the main data source. The evolving state of the atmosphere with time can be numerically predicted by solving a set of hydrodynamic equations, if the initial state is known. However, such a modelling approach always contains approximations that by and large depend on the purpose of use and resolution of the models. Present-day NWP systems operate with horizontal model resolutions in the range from about 40 km to 10 km. Recently, the aim has been to reach operationally to scales of 1 4 km. This requires less approximations in the model equations, more complex treatment of physical processes and, furthermore, more computing power. This thesis concentrates on the physical parameterization methods used in high-resolution NWP models. The main emphasis is on the validation of the grid-size-dependent convection parameterization in the High Resolution Limited Area Model (HIRLAM) and on a comprehensive intercomparison of radiative-flux parameterizations. In addition, the problems related to wind prediction near the coastline are addressed with high-resolution meso-scale models. The grid-size-dependent convection parameterization is clearly beneficial for NWP models operating with a dense grid. Results show that the current convection scheme in HIRLAM is still applicable down to a 5.6 km grid size. However, with further improved model resolution, the tendency of the model to overestimate strong precipitation intensities increases in all the experiment runs. For the clear-sky longwave radiation parameterization, schemes used in NWP-models provide much better results in comparison with simple empirical schemes. On the other hand, for the shortwave part of the spectrum, the empirical schemes are more competitive for producing fairly accurate surface fluxes. Overall, even the complex radiation parameterization schemes used in NWP-models seem to be slightly too transparent for both long- and shortwave radiation in clear-sky conditions. For cloudy conditions, simple cloud correction functions are tested. In case of longwave radiation, the empirical cloud correction methods provide rather accurate results, whereas for shortwave radiation the benefit is only marginal. Idealised high-resolution two-dimensional meso-scale model experiments suggest that the reason for the observed formation of the afternoon low level jet (LLJ) over the Gulf of Finland is an inertial oscillation mechanism, when the large-scale flow is from the south-east or west directions. The LLJ is further enhanced by the sea-breeze circulation. A three-dimensional HIRLAM experiment, with a 7.7 km grid size, is able to generate a similar LLJ flow structure as suggested by the 2D-experiments and observations. It is also pointed out that improved model resolution does not necessary lead to better wind forecasts in the statistical sense. In nested systems, the quality of the large-scale host model is really important, especially if the inner meso-scale model domain is small.

Esiselvitys Luoteis-Venäjän ja Kaakkois-Suomen aluetaloudellisesta, kulttuurisesta ja sosiaalisesta integraatiokehityksestä

Esiselvityksen tarkoituksena on esittää arvio Luoteis-Venäjän ja Kaakkois-Suomen integraation tämänhetkisestä tilanteesta sekä keskeisimmistä edellytyksistä ja esteistä. Raportin ensimmäisessä osassa käsitellään kohdealueiden taustaa, toisessa osassa integroitumisen edellytyksiä ja esteitä sekä kolmannessa osassa Kaakkois-Suomen mahdollisuuksia ja vetovoimatekijöitä. Luoteis-Venäjällä on ollut suuri merkitys Kaakkois-Suomen kehityksessä ja se nähdään edelleen suurimpana mahdollisuutena minkä suhteen alueella voidaan kehittyä. Suurimmiksi ongelmiksi haastattelujen perusteella nousivat bisnekseen itseensä perustuvat ongelmat sekä resurssien puute. Lisäksi kykenemättömyys sopeutua paikalliseen kulttuuriin, kielitaidon ja kulttuurintuntemuksen puute, asenneongelmat sekä Venäjällä kasvava protektionismi ja maan oikeusvaltiostatuksen puute nähtiin suurena esteenä. Sopimukset sekä Venäjällä toimiminen niin liiketoiminnassa kuin koulutus- ja tutkimussektorilla ovat saaneet mystisiä piirteitä. Integraation edellytyksinä esiin nousivat halu kansainvälistyä sekä valmius panostaa ajallisesti ja rahallisesti. Muut edellytykset riippuvat valitusta toimintamallista. Toimintaympäristöön integroitumisen edellytyksenä pidettiin toimivia suhteita paikallishallintoon ja henkilökunnan venäläistämistä. Suomalaisten menestymisen edellytyksiä pidettiin hyvänä. Koulutus- ja tutkimussektorilla esiin nousivat perusrahoituksen puuttuminen, Suomi-keskeisyys sekä asenneongelmat. Venäläinen partneri on kuitenkin olennainen ja yhteistoiminnan edellytyksenä pidettiin verkostojen luomista. Koulutusviennin osalta esiin nousivat johtamis- ja projektihallinnon tarjonta. Ongelmana nähtiin yliopistojen välinen kilpailu ja toiveena oli parempi yhteistoiminta korkeakoulujen kesken. Julkisen sektorin puolella suurimmaksi ongelmaksi nousivat toimijoiden suuri määrä sekä niiden välinen kilpailu Kaakkois-Suomessa ja Luoteis-Venäjällä. Myös Kouvolan ja Kotkan sekä rautatien ja E18-tien välinen kilpailu haittaavat alueen kehitystä. Lisäksi alueelta puuttuu poliittinen omistajuus asialle sekä vahva keulakuva. Integraation tulisi toteutua julkisen sektorin ja yritysten yhteistyönä. Valtiolta toivottiin viisumikysymyksen pikaista ratkaisua, eikä viisumin poistumisen mahdollisia negatiivisia vaikutuksia pidetty suurena ongelmana. Kymenlaakson rakennemuutos nähtiin mieluummin mahdollisuutena kuin haittana. Sen sijaan yliopiston puute luo leiman alueelle, ja LUT:n vaikutusta toivottiin koko Kaakkois-Suomeen. Alueen infran todettiin olevan toimiva ja kehittämiseen kaivattiin aloitteellisuutta sekä nopeita toimia. Logistiikkaan pidettiin Kaakkois-Suomen vahvuutena, mutta liiallisen keskittymisen rautateihin tai satamiin nähtiin hidastavan kehitystä. Toimijoiden toivottiin yhdistyvän ja muodostavan ketjuja sekä keskittyvän alueen omiin vahvuuksiin, joista toivottiin selvitystä. Alueen kehittämisen kannalta esiin nousi vaatimuksia korkeamasta palvelutasosta sekä kielen ja kulttuurin tuntemuksen lisäämisestä. Erityisesti matkailun alalle sekä kulttuurivaihtoon kaivattiin kehitystä, isoja hankkeita ja rajaseudun sekä omaa brändiä. Lisäksi Lappeenrannan lentokenttää ja nopeaa junayhteyttä tulisi hyödyntää enemmän, sekä panostaa matkailijoiden opastukseen. Alueen vetovoimatekijöinä nähtiin erilaiset terveys-, hoito- ja kuntoutuspalvelut, sekä huoltotoiminnot. Paperiteollisuuden puolella tulisi yhdistää ekologia, ekonomia ja teknologia sekä saada uusia innovaatioita. Lisäksi Kaakkois-Suomessa tulisi keskittyä logistiikkaan, digitaaliseen viestintään, uusiutuviin energioihin sekä tietointensiiviseen työhön. Alueen venäläisistä yrityksistä ja mahdollisista investointikohteista kaivattiin lisäselvityksiä. Integroituminen yhteiskuntaan vaatii poikkihallinnollisia toimita ja kielikoulutuksen aikaista aloittamista. Maakuntaliiton panostusta toivottiin erityisesti suhteiden luomiseen Suomessa ja Venäjällä, alueen logistiikan painopistealueiden määrittelemiseen sekä kulttuurisen integraation huomioimiseen strategioissaan.

Mapping Road Infrastructure in Developing Countries Applying Remote Sensing and GIS - The Case of the Taita Hills, Kenya

Road transport and infrastructure has a fundamental meaning for the developing world. Poor quality and inadequate coverage of roads, lack of maintenance operations and outdated road maps continue to hinder economic and social development in the developing countries. This thesis focuses on studying the present state of road infrastructure and its mapping in the Taita Hills, south-east Kenya. The study is included as a part of the TAITA-project by the Department of Geography, University of Helsinki. The road infrastructure of the study area is studied by remote sensing and GIS based methodology. As the principal dataset, true colour airborne digital camera data from 2004, was used to generate an aerial image mosaic of the study area. Auxiliary data includes SPOT satellite imagery from 2003, field spectrometry data of road surfaces and relevant literature. Road infrastructure characteristics are interpreted from three test sites using pixel-based supervised classification, object-oriented supervised classifications and visual interpretation. Road infrastructure of the test sites is interpreted visually from a SPOT image. Road centrelines are then extracted from the object-oriented classification results with an automatic vectorisation process. The road infrastructure of the entire image mosaic is mapped by applying the most appropriate assessed data and techniques. The spectral characteristics and reflectance of various road surfaces are considered with the acquired field spectra and relevant literature. The results are compared with the experimented road mapping methods. This study concludes that classification and extraction of roads remains a difficult task, and that the accuracy of the results is inadequate regardless of the high spatial resolution of the image mosaic used in this thesis. Visual interpretation, out of all the experimented methods in this thesis is the most straightforward, accurate and valid technique for road mapping. Certain road surfaces have similar spectral characteristics and reflectance values with other land cover and land use. This has a great influence for digital analysis techniques in particular. Road mapping is made even more complicated by rich vegetation and tree canopy, clouds, shadows, low contrast between roads and surroundings and the width of narrow roads in relation to the spatial resolution of the imagery used. The results of this thesis may be applied to road infrastructure mapping in developing countries on a more general context, although with certain limits. In particular, unclassified rural roads require updated road mapping schemas to intensify road transport possibilities and to assist in the development of the developing world.

Novel M-Superfamily and T-Superfamily conotoxins and contryphans from the vermivorous snail Conus figulinus

The venom of Conus figulinus, a vermivorous cone snail, found in the south east coast of India, has been studied in an effort to identify novel peptide toxins. The amino acid sequences of seven peptides have been established using de novo mass spectrometric based sequencing methods. Among these, three peptides belong to the M-Superfamily conotoxins, namely, Fi3a, Fi3b, and Fi3c, and one that belongs to the T-Superfamily, namely, Fi5a. The other three peptides are contryphans, namely, contryphans fib, fic, and fid. Of these Fi3b, Fi3c, Fi5a, and contryphan fib are novel and are reported for the first time from venom of C.figulinus. The details of the sequencing methods and the relationship of these peptides with other M'-Superfamily conotoxins from the fish hunting and mollusk hunting clades are discussed. These novel peptides could serve as a lead compounds for the development of neuropharmacologically important drugs. Copyright (c) 2014 European Peptide Society and John Wiley & Sons, Ltd.

Breeding in bamboo: a novel anuran reproductive strategy discovered in Rhacophorid frogs of the Western Ghats, India

Amphibians exhibit extraordinarily diverse sets of reproductive strategies among vertebrates. Understanding life history strategies in an evolutionary framework is lacking for many amphibian species in the tropics. Here, we report a novel reproductive mode where adult frogs enter hollow internodes of bamboo via a small opening, deposit direct developing eggs, and provide parental care. This behaviour is observed in two species of the frog genus Raorchestes. The first description of this unique life history and details of nest site characteristics and embryo development are provided along with ecological comparisons. Evolution of novel reproductive modes and parental care are discussed in context of natural selection. Dearth of natural history information on amphibians in the Western Ghats and much of the South-East Asian region is highlighted with suggestions for further studies.(c) 2014 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 114, 1-11.

An interdisciplinary framework to evaluate bioshield plantations: Insights from peninsular India

Bioshields or coastal vegetation structures are currently amongst the most important coastal habitat modification activities in south-east Asia, particularly after the December 2004 tsunami. Coastal plantations have been promoted at a large scale as protection against severe natural disasters despite considerable debate over their efficacy as protection measures. In this paper, we provide an interdisciplinary framework for evaluating and monitoring coastal plantations. We then use this framework in a case study in peninsular India. We conducted a socio-ecological questionnaire-based survey on government and non-government organizations directly involved in coastal plantation efforts in three 2004 Indian Ocean tsunami affected states in mainland India. We found that though coastal protection was stated to be the primary cause, socio-economic factors like providing rural employment were strong drivers of plantation activities. Local communities were engaged primarily as daily wage labour for plantation. rather than in the planning or monitoring phases. Application of ecological criteria has been undermined during the establishment and maintenance of plantations and there was a general lack of awareness about conservation laws relating to coastal forests. While ample flow of international aid has fuelled the plantation of exotics in the study area particularly after the Indian Ocean tsunami in 2004, the long term ecological consequences need further evaluation and rigorous monitoring in the future.

Primates, Provisioning and Plants: Impacts of Human Cultural Behaviours on Primate Ecological Functions

Human provisioning of wildlife with food is a widespread global practice that occurs in multiple socio-cultural circumstances. Provisioning may indirectly alter ecosystem functioning through changes in the eco-ethology of animals, but few studies have quantified this aspect. Provisioning of primates by humans is known to impact their activity budgets, diets and ranging patterns. Primates are also keystone species in tropical forests through their role as seed dispersers; yet there is no information on how provisioning might affect primate ecological functions. The rhesus macaque is a major human-commensal species but is also an important seed disperser in the wild. In this study, we investigated the potential impacts of provisioning on the role of rhesus macaques as seed dispersers in the Buxa Tiger Reserve, India. We studied a troop of macaques which were provisioned for a part of the year and were dependent on natural resources for the rest. We observed feeding behaviour, seed handling techniques and ranging patterns of the macaques and monitored availability of wild fruits. Irrespective of fruit availability, frugivory and seed dispersal activities decreased when the macaques were provisioned. Provisioned macaques also had shortened daily ranges implying shorter dispersal distances. Finally, during provisioning periods, seeds were deposited on tarmac roads that were unconducive for germination. Provisioning promotes human-primate conflict, as commensal primates are often involved in aggressive encounters with humans over resources, leading to negative consequences for both parties involved. Preventing or curbing provisioning is not an easy task as feeding wild animals is a socio-cultural tradition across much of South and South-East Asia, including India. We recommend the initiation of literacy programmes that educate lay citizens about the ill-effects of provisioning and strongly caution them against the practice.

Fang, Anlandungen, Discard und Bestand der Nordsee-garnele (Crangon crangon L.)

Landings of brown shrimp (Crangon crangon) for human consumption are not the only part that is taken from the North Sea shrimp stocks. Small amounts of industrial shrimps taken in the second half of a year in Germany add as well to the total amount that is taken from the stocks as the moribund animals discarded all over the year during the first sieving process on board, as the cooked and discarded ones in the second sieving on board and as those from the third sieving process ashore normally being crushed and used for animal feed stuff. All these fractions of the total catch of brown shrimps give a total of approximately 74 000 tonnes that were taken from the North Sea in 2005. Nevertheless, due to low predator abundance and changing climate conditions Crangon stocks show no signs of overexploitation so far with increasing LPUE values in the north-eastern part of the German Bight and decreasing ones in the south-east and Channel. There is the need of further investigations of these changes in the life history and distribution of shrimp as well as in the fishing behaviour and effort of the shrimp fleets .

The impact of year-to-year changes in the weather on the seasonal dynamics of lakes

Year-to-year changes in the weather have a pronounced effect on the quality of the water abstracted from many reservoirs in the UK. In upland reservoirs, the most common weather-related problem is the appearance of coloured water following dry summers and the re-wetting of peat during the winter (Naden & McDonald 1989; George 2000). In lowland reservoirs, the most serious weather-related issue is the growth of bloom- forming species of algae during warm, calm summers (National Rivers Authority 1989). Both of these problems are likely to get worse as the climate becomes warmer and extreme variations in the weather become more common. In this article, the authors describe some of the ways in which recent changes in the weather have influenced the quality of the water stored in a large reservoir in the south-east of England. The reservoir selected for study is the Queen Elizabeth II (QEII), a bankside reservoir situated in the Thames valley. The quality of water stored in this reservoir is generally very good but summer blooms of algae have become increasingly common in recent years.

New challenges in lake and river monitoring

Freshwater ecosystems are highly dynamic and change on time-scales that range from a few hours to several months. The development of models that simulate these processes is often hampered by the lack of sufficient data to parameterize the processes and validate the models. In this article, I review some of the challenges posed by this lack of information and suggest ways in which they can be met by using automatic monitoring systems. One of these studies is the project tempQsim (EVK1-CT2002-00112) funded by the European Commission. In this project, detailed field and model analyses have been performed at eight catchment study sites in south and south-east Europe. A number of perceptual models for the study sites have been established, and results are being used to improve selected catchment models and provide a more adequate description of pollution dynamics. Results from the extensive field studies and model tests are now being used to derive recommendations for more tailored monitoring concepts in highly dynamic, but ‘data scarce’ environments, such as are frequently found in Mediterranean river basins. The author includes implications of the EU Water Framework Directive on monitoring methods.

Les acadjas traditionnels dans le sud-est du Bénin

This study mission on acadja, the traditional way of fishing in the lagoons of the South-East part of Benin, permits us to understand how well-established this fishing practice is, in terms of time and spatial extention. The exploitation of acadja has a great profitability but it also represents the source of some problems as deterioration of branches, deforestation and social conflits. However, when acadjas are rationally exploited, they constitute a hope for waters which are in the process of losing their biological richness.

Avaliação ambiental através da utilização do fitoplâncton. Estudo de caso: Ilha Guaíba Mangaratiba RJ.

A Baía da Ilha Guaíba é um sistema costeiro tropical com influência de águas oceânicas, principalmente da Corrente do Brasil e das Águas Costeiras que são predominantes em toda a costa da região sudeste. O objetivo geral foi identificar os indicadores biológicos das possíveis alterações ambientais e ou antrópicas e como objetivos específicos, apresentar a distribuição qualitativa e quantitativa do fitoplâncton em função da espacialidade e da sazonalidade em duas situações de maré bem como demonstrar a estrutura da comunidade fitoplanctônica dentro de um Programa de Monitoramento desenvolvido pela empresa Minerações Brasileiras Reunidas através do Centro de Tecnologia Ambiental da FIRJAN (CTA). Foram estabelecidos 9 pontos amostrais na área sob influência do Terminal Marítimo da Ilha levando em consideração as características de cada um. Para o estudo qualitativo e quantitativo do fitoplâncton, 200 ml de água foram coletados em dois pontos de amostragem 7 e 9 em baixa-mar e preamar, através de garrafa de Van Dorn e nos 9 pontos foi realizado arrasto com rede de 50μm, ambos em quatro épocas sazonais distintas. Ao todo foram encontradas 176 unidades taxonômicas demonstrando uma importante oferta de nichos. A espécie que mais se destacou foi Coscinodiscus cf. centralis em todas as amostras de rede. A sazonalidade foi vista através de uma análise de Cluster tanto para as amostras de rede quanto para as de garrafa. Não houve registro de espécies que indicassem alterações antrópicas não revelando condição de eutrofização. Foram encontradas espécies indicadoras de diferentes massas de água como também outras potencialmente nocivas. Os resultados bióticos e abióticos demonstraram que a área sob influência do empreendimento está dentro dos padrões estabelecidos pela legislação vigente e que para o estabelecimento de um desenvolvimento sustentável torna-se imprescindível a adoção de métodos padronizados e multiinterdisciplinares para que seja possível comparar e acompanhar os processos e seus efeitos viabilizando assim a manutenção da biodiversidade.
