An ECOOP web portal for visualising and comparing distributed coastal oceanography model and in situ data

As part of a large European coastal operational oceanography project (ECOOP), we have developed a web portal for the display and comparison of model and in situ marine data. The distributed model and in situ datasets are accessed via an Open Geospatial Consortium Web Map Service (WMS) and Web Feature Service (WFS) respectively. These services were developed independently and readily integrated for the purposes of the ECOOP project, illustrating the ease of interoperability resulting from adherence to international standards. The key feature of the portal is the ability to display co-plotted timeseries of the in situ and model data and the quantification of misfits between the two. By using standards-based web technology we allow the user to quickly and easily explore over twenty model data feeds and compare these with dozens of in situ data feeds without being concerned with the low level details of differing file formats or the physical location of the data. Scientific and operational benefits to this work include model validation, quality control of observations, data assimilation and decision support in near real time. In these areas it is essential to be able to bring different data streams together from often disparate locations

Volunteer tourism : the new ecotourism?

One of the more recent forms of tourism to emerge is what has become known as Volunteer Tourism, the practice of individuals going on a working holiday, volunteering their labour for worthy causes. While volunteering is a well-established activity, the combination with tourism is relatively new and has already changed considerably over a very short period. This paper reviews the process by which volunteer tourism has developed, focusing on its transformation from an individual altruistic endeavour to a more commercial form of conventional tourism. The paper reviews the growth in number of websites devoted to volunteer tourism, and discusses the changes that have taken place in the content and focus of these websites, the locations used as destinations and the organisations they represent over the last two decades. It is apparent that over the last two decades the organisations offering volunteer tourist vacations have increasingly focused their attention on conventional commercial tourism markets which is a similar pattern of evolution to that of ecotourism. The paper concludes that volunteer tourism is likely to become increasingly diverse in scale, distribution and focus in the future, in the same way as ecotourism has broadened its market and appeal, but in so doing, will lose more of the distinctive features that characterized its initial form

Scale insects (Hemiptera: Coccoidea) of ornamental plants from Sao Carlos, Sao Paulo, Brazil

A list of 35 scale insects collected from 72 ornamental plant species in Sao Carlos, Sao Paulo, Brazil is provided. Regarding host specificity, 30 scale insects were polyphagous, 4 oligophagous, and 1 monophagous. A total of 102 coccoid/plant associations are recorded, 29 of which are new host records for the species; 60 are new host records for the species in Brazil. Pulvinaria urbicola Cockerell, 1893 (Coccidae), Phenacoccus similis Granara de Willink, 1983 (Pseudococcidae), and Orthezia molinarii (Morrison, 1952) (Ortheziidae) are recorded for the first time in Brazil. In addition, we describe the injury caused by scale insects on ornamental plants

Environmental Issues and Farming in Developing Countries

Formerly a rich-county preoccupation, dealing more explicitly with environmental concerns around agriculture is becoming a mainstream concern for developing countries. Concerns arise with all the major resources underpinning farming, such as land and water which are selectively reviewed here but most attention is concentrated on the soil resource and carbon sequestration possibilities. The results of some environmental interventions constitute public goods at variously local, regional and global levels and thus provide a rationale for potential engagement for governments and development agencies.Environmental Economics and Policy, Farm Management, Land Economics/Use,

On Mourning and Recovery: Integrating Stages of Grief and Change Toward a Neuroscience-Based Model of Attachment Adaptation in Addiction Treatment

Interpersonal attachment and drug addiction share many attributes across their behavioral and neurobiological domains. Understanding the overlapping brain circuitry of attachment formation and addiction illuminates a deeper understanding of the pathogenesis of trauma-related mental illnesses and comorbid substance use disorders, and the extent to which ending an addiction is complicated by being a sort of mourning process. Attention to the process of addiction recovery—as a form of grieving—in which Kubler-Ross's stages of grief and Prochaska's stages of change are ultimately describing complementary viewpoints on a general process of neural network and attachment remodeling, could lead to more effective and integrative psychotherapy and medication strategies

Ganoderma disease of oil palm : a white rot perspective necessary for integrated control

White rot fungi such as Ganoderma, are extraordinary organisms capable exclusively of degrading lignin to carbon dioxide and water: celluloses are then available as nutrients for the fungus. Oil palm (OP) is a highly significant crop in many countries and is prone to a rot caused by the fungus. It is necessary to consider this mode of attack as a white rot involving lignin biodegradation, for integrated control. The existing literature does not report this area and appears to be concerned particularly with the mode of spread and molecular biology of Ganoderma. The white rot perception opens up new fields such as (a) especially breeding/selecting for resistant cultivars of OP with high lignin content, (b) ensuring that the conditions for lignin decomposition are reduced, and (c) simply sealing damaged OP specifically to stop decay. It is likely that spread is by spores rather than roots. The knowledge gained can be employed in the rapid degradation of OP waste on the plantation floor by inoculating suitable fungi, and/or treating the waste more appropriately (e.g. chipping and spreading over the floor rather than windrowing). In conclusion, the control of Ganoderma on OP would benefit from further consideration of the process as one of white rot.Fundação para a Ciência e a Tecnologia (FCT

Logistic modelling of smallholder livestock farmers’ adoption of tree-based fodder technology in Zimbabwe

Based on field data collected from 131 small scale dairy farmers that were randomly selected from four agro-ecological zones, this study assessed the potential of adoption of fodder bank technology as a means for improving livestock production and income generation for smallholder farmers in Zimbabwe. Using a logit modelling approach, it also identified the drivers of adoption of the technology by analysing the influence of household characteristics and ecological factors on farmers’ decision to adopt the technology. The model correctly predicted 75% of observed adoption and non-adoption by farmers. Results reveal that dairy herd size, land holding size, membership of dairy association and agro-ecological potential are the key factors influencing farmers’ adoption of fodder bank. Age, sex, household size and educational level of farmers play lesser role. Male and female farmers were equally likely to take up and practice fodder bank if they are given equal access to information and incentives. The study recommends farmer-led extension approaches where farmers who possess certain key characteristics should constitute the initial group for disseminating information regarding the technology in rural communities. The results highlight the importance of access to dairy product markets as a driver for the adoption of fodder banks. It is recommended that forging a strategic partnership with the Dairy Development Programme (DDP) will offer high potential for enhancing the scaling up of the adoption and impact of fodder bank technology in the country.Livestock Production/Industries, Research and Development/Tech Change/Emerging Technologies,
